Create Circuits and VT Tunnels

Note The terms “Unidirectional Path Switched Ring” and “UPSR” may appear in Cisco literature. These terms do not refer to using Cisco ONS 15xxx products in a unidirectional path switched ring configuration. Rather, these terms, as well as “Path Protected Mesh Network” and “PPMN,” refer generally to Cisco's path protection feature, which may be used in any topological network configuration. Cisco does not recommend using its path protection feature in any particular topological network configuration.

The circuit destination is where the circuit exits an ONS 15454 network.

Automatic circuit routing

Cisco Transport Controller (CTC) routes the circuit automatically on the shortest available path based on routing parameters and bandwidth availability.

Manual circuit routing

Manual routing allows you to choose a specific path, not just the shortest path chosen by automatic routing. You can choose a specific synchronous transport signal (STS) or Virtual Tributary (VT) for each circuit segment and create circuits from work orders prepared by an operations support system (OSS) like the Telcordia Trunk Information Record Keeping System (TIRKS).

VT aggregation points (VAPs) allow VT circuits to be aggregated into an STS for handoff to non-ONS 15454 networks or equipment, such as interoffice facilities (IOFs), switches, or digital access and cross-connect systems (DACS). VAPs reduce VT matrix resource utilization at the node where the VTs are aggregated onto the STS. This node is called the STS grooming end. The STS grooming end requires an EC1, DS3, DS3E, DS3/EC1-48, DS3XM-6, DS3XM-12, or OC-N card. VAPs can be created on BLSR, 1+1, or unprotected nodes, but cannot be created on path protection nodes.

4.You can route one STS circuit on a DS1 card to carry all 14 ports within the STS. However, 14 VT1.5s are not utilized.

5.The number of “portless” interfaces depends on the system configuration. For XCVT drop slots, a maximum of 6 portless transmultiplexing interfaces are supported. For XCVT trunk slots and for the XC10G and XC-VXC-10G any slot, a maximum of 12 portless transmultiplexing interfaces are supported.

6.The CE-MR-10 card supports 48 STSs when it is installed in Slot 1 to 4 or 14 to 17, and supports 192 STSs when it is installed in Slot 5, 6, 12, or 13.

7.The CE-MR-10 card supports 48 STSs when it is installed in Slot 1 to 4 or 14 to 17, and supports 192 STSs when it is installed in Slot 5, 6, 12, or 13.

8.Dependent on the SFP used in a port, the available backplane width, and existing provisioned lines. For more details, refer to the “Optical Cards” chapter in the Cisco ONS 15454 Reference Manual.

NTP-A127 Verify Network Turn Up

Purpose

This procedure verifies that the ONS 15454 network is ready for circuit provisioning.

Step 2From the View menu, choose Go to Network View. Wait for all the nodes that are part of the network to appear on the network map. (Large networks might take several minutes to display all the nodes.)

Note If this is the first time your computer has connected to this ONS 15454 network, the node icons are stacked on the left side of the graphic area, possibly out of view. Use the scroll bar under the network map to display the icons. To separate the icons, drag and drop the icon to the new location. Repeat until all the nodes are visible on the graphic area.

Step 3Verify node accessibility. In network view, all node icons must be either green, yellow, orange, or red.

If all network nodes do not appear after a few minutes, or if a node icon is gray with “Unknown” under it, do not continue. Look at the Net box in the lower right corner of the window. If it is gray, log in again, making sure not to check the Disable Network check box in the CTC Login dialog box. If problems persist, see Chapter 5, “Turn Up a Network” to review the network turn-up procedure appropriate for your network topology, or refer to the Cisco ONS 15454 Troubleshooting Guide for troubleshooting procedures.

Step 4 Verify DCC connectivity. All nodes must be connected by green lines. If lines are missing or gray in color, do not continue. See Chapter 5, “Turn Up a Network” and follow the network turn-up procedure appropriate for your network topology. Verify that all nodes have DCC connectivity before continuing.

Step 6From the View menu, choose Go to Home View. Verify that the node is provisioned according to your site or engineering plan:

a. View the cards in the shelf map. Verify that the ONS 15454 cards appear in the specified slots.

b. Click the Provisioning > General tabs. Verify that the node name, contacts, date, time, and Network Time Protocol/Simple Network Time Protocol (NTP/SNTP) server IP address (if used) are correctly provisioned. If needed, make corrections using the A25 Set Up Name, Date, Time, and Contact Information.

c. Click the Network tab. Verify that the IP address, Subnet Mask, Default Router, Prevent LCD IP Config, and Gateway Settings are correctly provisioned. If not, make corrections using the A169 Set Up CTC Network Access.

d. Click the Protection tab. Verify that protection groups are created as specified in your site plan. If the protection groups are not created, complete the A324 Create Protection Groups.

e. If the node is in a BLSR, click the BLSR tab. (If the node is not in a BLSR, continue with Step f.) Verify that the following items are provisioned as specified in your site plan:

g. If Simple Network Management Protocol (SNMP) is used, click the SNMP tab and verify the trap and destination information. If the information is not correct, see the A87 Change SNMP Settings to correct the information.

h. Click the Comm Channels tab. Verify that DCCs were created to the applicable OC-N slots and ports (time-division multiplexing [TDM] nodes) or optical service channel (OSC) slots and ports (dense wavelength division multiplexing [DWDM] nodes). If DCCs were not created for the appropriate OC-N or OSC slots and ports, see Chapter 5, “Turn Up a Network” and complete the turn-up procedure appropriate for your network topology. To provision OSC ports, refer to the Cisco ONS 15454 DWDM Procedure Guide

i. Click the Timing tab. Verify that timing is provisioned as specified. If not, use the A85 Change Node Timing to make the changes.

Note This procedure requires the use of automatic routing. Automatic routing is not available if both the Automatic Circuit Routing NE default and the Network Circuit Automatic Routing Overridable NE default are set to FALSE. For a full description of these defaults see the “Network Element Defaults” appendix in the Cisco ONS 15454 Reference Manual.

Step 1 Complete the A60 Log into CTC at the node where you will create the circuit. If you are already logged in, continue with Step 2.

Step 2If you want to assign a name to the circuit source and destination ports before you create the circuit, complete the A314 Assign a Name to a Port. If not, continue with Step 3.

Number of Circuits—Enter the number of DS-1 circuits that you want to create. The default is 1. If you are creating multiple circuits with the same slot and sequential port numbers, you can use Auto-ranged to create the circuits automatically.

Auto-ranged—This check box is automatically selected if you enter more than 1 in the Number of Circuits field. Auto-ranging creates identical (same source and destination) sequential circuits automatically. Uncheck the box if you do not want CTC to create sequential circuits automatically.

Name—Assign a name to the circuit. The name can be alphanumeric and up to 48 characters, (including spaces). Circuit names should be 43 characters or less if you want the ability to create monitor circuits. If you leave the field blank, CTC assigns a default name to the circuit.

Size—If the circuit type is VT, choose VT1.5. If the circuit type is STS, choose STS-1.

Bidirectional—Leave checked for this circuit (default).

Create cross-connects only (TL1-like)—Check this box if you want to create one or more cross-connects to complete a signal path for TL1-generated circuits. If you check this box, VT tunnels and Ethergroup sources and destinations are unavailable.

Diagnostic—Leave unchecked.

State—Choose the administrative state to apply to all of the cross-connects in a circuit:

– IS—Puts the circuit cross-connects in the In-Service and Normal (IS-NR) service state.

– OOS,DSBLD—Puts the circuit cross-connects in the Out-of-Service and Management, Disabled (OOS-MA,DSBLD) service state. Traffic is not passed on the circuit.

– IS,AINS—Puts the circuit cross-connects in the Out-of-Service and Autonomous, Automatic In-Service (OOS-AU,AINS) service state and suppresses alarms and conditions. When the connections receive a valid signal, the service state automatically changes to IS-NR.

– OOS,MT—Puts the circuit cross-connects in the Out-of-Service and Management, Maintenance (OOS-MA,MT) service state. The maintenance state does not interrupt traffic flow; it suppresses alarms and conditions and allows loopbacks to be performed on the circuit. Use OOS,MT for circuit testing or to suppress circuit alarms temporarily. Change the administrative state to IS; IS,AINS; or OOS,DSBLD when testing is complete. See the A230 Change a Circuit Service State.

For additional information about circuit service states, refer to the “Circuits and Tunnels” chapter in the Cisco ONS 15454 Reference Manual.

Apply to drop ports—Check this check box if you want to apply the administrative state chosen in the State field to the circuit source and destination ports. CTC applies the administrative state to the ports only if the circuit bandwidth is the same as the port bandwidth or, if the port bandwidth is larger than the circuit, the circuit must be the first circuit to use the port. If not, a Warning dialog box displays the ports where the administrative state could not be applied. If the check box is unchecked, CTC does not apply the administrative state to the source and destination ports.

Note If ports managed into the IS administrative state are not receiving signals, loss of signal alarms are generated and the port service state transitions to OOS-AU,FLT.

Protected Drops—Check this box if you want the circuit routed on protected drops only, that is, to ONS 15454 cards that are in 1:1, 1:N, 1+1, or optimized 1+1 protection. If you check this box, CTC displays only protected cards and ports as source and destination choices.

Using Required Nodes/Spans—Check this check box if you want to specify nodes and spans to include or exclude in the CTC-generated circuit route.

Including nodes and spans for a circuit ensures that those nodes and spans are in the working path of the circuit (but not the protect path). Excluding nodes and spans ensures that the nodes and spans are not in the working or protect path of the circuit.

Review Route Before Creation—Check this check box if you want to review and edit the circuit route before the circuit is created.

Figure 6-2 Setting Circuit Routing Preferences for a DS-1 Circuit

Step 12To set the circuit path protection, complete one of the following:

To route the circuit on a protected path, leave Fully Protected Path checked and continue with Step 13. CTC creates a fully protected circuit route based on the path diversity option you choose. Fully protected paths might or might not have path protection path segments (with primary and alternate paths), and the path diversity options apply only to path protection path segments, if any exist.

Caution Circuits routed on BLSR protection channels are not protected. They are preempted during BLSR switches.

Step 13If you selected Fully Protected Path in Step 12 and the circuit will be routed on a path protection configuration, choose one of the following:

Nodal Diversity Required—Ensures that the primary and alternate paths within path protection portions of the complete circuit path are nodally diverse.

Nodal Diversity Desired—Specifies that node diversity is preferred, but if node diversity is not possible, CTC creates fiber-diverse paths for the path protection portion of the complete circuit path.

Link Diversity Only—Specifies that only fiber-diverse primary and alternate paths for path protection portions of the complete circuit path are needed. The paths might be node-diverse, but CTC does not check for node diversity.

Step 14If you selected Fully Protected Path in Step 12 and the circuit will be routed on a BLSR or path protection dual-ring interconnect (DRI), check the Dual Ring Interconnect check box.

Step 15If you checked Using Required Nodes/Spans in Step 11 or Dual Ring Interconnect for a path protection configuration in Step 14, complete the following substeps. If you checked Dual Ring Interconnect for a BLSR, skip this step and continue with Step 16. If you did not select any of these options, continue with Step 17.

a. In the Circuit Constraints for Automatic Routing area, click a node or span on the circuit map.

b. Click Include to include the node or span in the circuit. Click Exclude to exclude the node or span from the circuit. The order in which you choose included nodes and spans is the order in which the circuit is routed. Click spans twice to change the circuit direction.

c. Repeat Step b for each node or span you wish to include or exclude.

d. Review the circuit route. To change the circuit routing order, choose a node in the Required Nodes/Lines or Excluded Nodes Links lists and click the Up or Down buttons to change the circuit routing order. Click Remove to remove a node or span.

Step 17Click Next. If you are creating VT circuits, in the Create area of the VT Matrix Optimization page choose one of the following options. If not, continue with Step 18.

Create VT tunnel on transit nodes—This option is available if the DS-1 circuit passes through a node that does not have a VT tunnel, or if an existing VT tunnel is full. VT tunnels allow VT circuits to pass through ONS 15454s without consuming cross-connect card resources. VT tunnels can carry 28 VT1.5 circuits. In general, creating VT tunnels is a good idea if you are creating many VT circuits from the same source and destination. Refer to the Cisco ONS 15454 Reference Manual for more information.

Create VT aggregation point—This option is available if the DS-1 circuit source or destination is on an EC1, DS3, DS3E, DS3i-N-12, DS3/EC1-48, DS3XM-6, DS3XM-12, or OC-N port on a BLSR, 1+1, or unprotected node. VAPs collect DS-1s on an STS for handoff to non-ONS 15454 networks or equipment, such as an IOF, switch, or DACS. It allows VT1.5 circuits to be routed through the node using one STS connection on the cross-connect card matrix rather than multiple VT connections on the cross-connect card VT matrix. If you want to aggregate the DS-1 circuit you are creating with others onto an STS for transport outside the ONS 15454 network, choose one of the following:

– STS grooming node is source node, VT grooming node is destination node —Creates the VAP on the DS-1 circuit source node. This option is available only if the DS-1 circuit originates on an EC1, DS3, DS3E, DS3i-N-12, DS3/EC1-48, DS3XM-6, DS3XM-12, or OC-N card.

– STS grooming node is destination node, VT grooming node is source node —Creates the VAP on the DS-1 circuit destination node. This option is available only if the DS-1 circuit terminates on an EC1, DS3, DS3E, DS3i-N-12, DS3/EC1-48, DS3XM-6, DS3XM-12, or OC-N card.

None—Choose this option if you do not want to create a VT tunnel or a VAP. This is the only available option if CTC cannot create a VT tunnel or VAP.

Step 18If you selected Review Route Before Creation in Step 11, complete the following substeps. If not, continue with Step 19.

a. Click Next.

b. Review the circuit route. To add or delete a circuit span, choose a node on the circuit route. Blue arrows show the circuit route. Green arrows indicate spans that you can add. Click a span arrowhead, then click Include to include the span or Remove to remove the span.

c. If the provisioned circuit does not reflect the routing and configuration you want, click Back to verify and change circuit information. If the circuit needs to be routed to a different path, see the A182 Create a Manually Routed DS-1 Circuit.

Step 19Click Finish. One of the following results occurs if you entered more than one circuit in the Number of Circuits field on the Circuit Creation dialog box.

If you chose Auto-ranged, CTC automatically creates the number of circuits entered in the Number of Circuits field. If auto-ranging cannot complete all the circuits, for example, because sequential ports are unavailable at the source or destination, a dialog box appears. Set the new source or destination for the remaining circuits, then click Finish to continue auto-ranging. After completing the circuits, the Circuits window appears.

If you did not choose Auto-ranged, the Circuit Creation dialog box appears so you can create the remaining circuits. Repeat Steps 5 through 18 for each additional circuit. After completing the circuits, the Circuits window appears.

Step 20 In the Circuits window, verify that the new circuits appear in the circuits list.

Number of Circuits—Enter the number of DS-1 circuits that you want to create. The default is 1.

Auto-ranged—(Automatically routed circuits only) If you entered more than 1 in the Number of Circuits field on the Circuit Creation dialog box, uncheck this box. (The box is unavailable if only one circuit is entered in the Number of Circuits field.)

Name—Assign a name to the circuit. The name can be alphanumeric and up to 48 characters (including spaces). Circuit names should be 43 characters or less if you want the ability to create monitor circuits. If you leave the field blank, CTC assigns a default name to the circuit.

Size—If the circuit type is VT, choose VT1.5. If the circuit type is STS, choose STS-1.

Bidirectional—Leave checked for this circuit (default).

Create cross-connects only (TL1-like)—Check this box if you want to create one or more cross-connects to complete a signal path for TL1-generated circuits. If you check this box, VT tunnels and Ethergroup sources and destinations are unavailable.

State—Choose the administrative state to apply to all of the cross-connects in a circuit:

– IS—Puts the circuit cross-connects in the IS-NR service state.

– OOS,DSBLD—Puts the circuit cross-connects in the OOS-MA,DSBLD service state. Traffic is not passed on the circuit.

– IS,AINS—Puts the circuit cross-connects in the OOS-AU,AINS service state and suppresses alarms and conditions. When the connections receive a valid signal, the service state automatically changes to IS-NR.

– OOS,MT—Puts the circuit cross-connects in the OOS-MA,MT service state. The maintenance state does not interrupt traffic flow; it suppresses alarms and conditions and allows loopbacks to be performed on the circuit. Use OOS,MT for circuit testing or to suppress circuit alarms temporarily. Change the administrative state to IS; IS,AINS; or OOS,DSBLD when testing is complete. See the A230 Change a Circuit Service State.

For additional information about circuit service states, refer to the “Circuits and Tunnels” chapter in the Cisco ONS 15454 Reference Manual.

Apply to drop ports—Check this check box if you want to apply the administrative state chosen in the State field to the circuit source and destination ports. CTC applies the administrative state to the ports only if the circuit bandwidth is the same as the port bandwidth or, if the port bandwidth is larger than the circuit, the circuit must be the first circuit to use the port. If not, a Warning dialog box displays the ports where the administrative state could not be applied. If the check box is unchecked, CTC does not apply the administrative state to the source and destination ports.

Note If ports managed into the IS administrative state are not receiving signals, loss of signal alarms are generated and the port service state transitions to OOS-AU,FLT.

Protected Drops—Check this box if you want the circuit routed on protected drops only, that is, to ONS 15454 cards that are in 1:1, 1:N, 1+1, or optimized 1+1 protection. If you check this box, CTC shows only protected cards and ports as source and destination choices.

Step 12To set the circuit path protection, complete one of the following:

To route the circuit on a protected path, leave Fully Protected Path checked and continue with Step 13. Fully protected paths might or might not have path protection path segments (with primary and alternate paths), and the path diversity options apply only to path protection path segments, if any exist.

Caution Circuits routed on BLSR protection channels are not protected and are preempted during BLSR switches.

Step 13If you selected Fully Protected Path in Step 12 and the circuit will be routed on a path protection configuration, choose a Node-Diverse Path option:

Nodal Diversity Required—Ensures that the primary and alternate paths within the path protection portions of the complete circuit path are nodally diverse.

Nodal Diversity Desired— Specifies that node diversity is preferred, but if node diversity is not possible, CTC creates fiber-diverse paths for the path protection portion of the complete circuit path.

Link Diversity Only—Specifies that only fiber-diverse primary and alternate paths for path protection portions of the complete circuit path are needed. The paths might be node-diverse, but CTC does not check for node diversity.

Step 14 If you selected Fully Protected Path in Step 12 and the circuit will be routed on a path protection DRI or BLSR DRI, check the Dual Ring Interconnect check box.

Step 15 Click Next. In the Create area of the VT Matrix Optimization page, choose one of the following:

Create VT tunnel on transit nodes—This option is available if the DS-1 circuit passes through a node that does not have a VT tunnel, or if an existing VT tunnel is full. VT tunnels allow VT circuits to pass through ONS 15454s without consuming cross-connect card resources. VT tunnels can carry 28 VT1.5 circuits. In general, creating VT tunnels is a good idea if you are creating many VT circuits from the same source and destination. Refer to the Cisco ONS 15454 Reference Manual for more information.

Create VT aggregation point—This option is available if the DS-1 circuit source or destination is on an EC1, DS3, DS3E, DS3i-N-12, DS3/EC1-48, DS3XM-6, DS3XM-12, or OC-N port on a BLSR, 1+1, or unprotected node. VAPs collect DS-1s on an STS for handoff to non-ONS 15454 networks or equipment, such as an IOF, switch, or DACS. It allows VT1.5 circuits to be routed through the node using one STS connection on the cross-connect card matrix rather than multiple VT connections on the cross-connect card VT matrix. If you want to aggregate the DS-1 circuit you are creating with others onto an STS for transport outside the ONS 15454 network, choose one of the following:

– STS grooming node is source node, VT grooming node is destination node —Creates the VAP on the DS-1 circuit source node. This option is available only if the DS-1 circuit originates on an EC1, DS3, DS3E, DS3i-N-12, DS3XM-6, DS3XM-12, or OC-N card.

– STS grooming node is destination node, VT grooming node is source node —Creates the VAP on the DS-1 circuit destination node. This option is available only if the DS-1 circuit terminates on an EC1, DS3, DS3E, DS3i-N-12, DS3XM-6, DS3XM-12, or OC-N card.

None—Choose this option if you do not want to create a VT tunnel or a VAP. This is the only available option if CTC cannot create a VT tunnel or VAP.

Step 16Click Next. In the Route Review/Edit area, node icons appear for you to route the circuit manually. If you checked Dual Ring Interconnect for BLSR, continue with Step 17. If not, continue with Step 16.

Step 19Click Finish. CTC compares your manually provisioned circuit route with the specified path diversity option you chose in Step 13. If the path does not meet the specified path diversity requirement, CTC displays an error message and allows you to change the circuit path.

Step 20 If you entered more than 1 in the Number of Circuits field on the Circuit Creation dialog box, the Circuit Creation dialog box appears so you can create the remaining circuits. Repeat Steps 5 through 19 for each additional circuit.

Step 21 When all the circuits are created, the main Circuits window appears. Verify that the circuits you created are correct.

Name—Assign a name to the circuit. The name can be alphanumeric and up to 48 characters (including spaces). Circuit names should be 43 characters or less if you want the ability to create monitor circuits. If you leave the field blank, CTC assigns a default name to the circuit.

Size—If the circuit type is VT, choose VT1.5. If the circuit type is STS, choose STS-1.

Bidirectional—Uncheck for this circuit.

Create cross-connects only (TL1-like)—Check this box if you want to create one or more cross-connects to complete a signal path for TL1-generated circuits. If you check this box, VT tunnels and Ethergroup sources and destinations are unavailable.

Diagnostic—Leave unchecked.

State—Choose the administrative state to apply to all of the cross-connects in a circuit:

– IS—Puts the circuit cross-connects in the IS-NR service state.

– OOS,DSBLD—Puts the circuit cross-connects in the OOS-MA,DSBLD service state. Traffic is not passed on the circuit.

– IS,AINS—Puts the circuit cross-connects in the OOS-AU,AINS service state and suppresses alarms and conditions. When the connections receive a valid signal, the service state automatically changes to IS-NR.

– OOS,MT—Puts the circuit cross-connects in the OOS-MA,MT service state. The maintenance state does not interrupt traffic flow; it suppresses alarms and conditions and allows loopbacks to be performed on the circuit. Use OOS,MT for circuit testing or to suppress circuit alarms temporarily. Change the administrative state to IS; IS,AINS; or OOS,DSBLD when testing is complete. See the A230 Change a Circuit Service State.

For additional information about circuit service states, refer to the “Circuits and Tunnels” chapter in the Cisco ONS 15454 Reference Manual.

Apply to drop ports—Check this check box if you want to apply the administrative state chosen in the State field to the circuit source and destination ports. CTC applies the administrative state to the ports only if the circuit bandwidth is the same as the port bandwidth or, if the port bandwidth is larger than the circuit, the circuit must be the first circuit to use the port. If not, a Warning dialog box displays the ports where the administrative state could not be applied. If the check box is unchecked, CTC does not apply the administrative state to the source and destination ports.

Note If ports managed into the IS administrative state are not receiving signals, loss of signal alarms are generated and the port service state transitions to OOS-AU,FLT.

Protected Drops—Check this box if you want the circuit routed to protect drops only, that is, to ONS 15454 cards that are in 1:1, 1:N, 1+1, or optimized 1+1 protection. If you check this box, CTC displays only protected cards as source and destination choices.

Step 10 In the Circuit Routing Preferences area, uncheck Route Automatically. When Route Automatically is not selected, the Using Required Nodes/Spans and Review Route Before Circuit Creation check boxes are unavailable.

Step 11To set the circuit path protection, complete one of the following:

To route the circuit on a protected path, leave Fully Protected Path checked and continue with Step 12. Fully protected paths might or might not have path protection path segments (with primary and alternate paths), and the path diversity options apply only to path protection path segments, if any exist.

Caution Circuits routed on BLSR protection channels are not protected and are preempted during BLSR switches.

Step 12If you selected Fully Protected Path in Step 11 and the circuit will be routed on a path protection configuration, choose one of the following:

Nodal Diversity Required—Ensures that the primary and alternate paths within the path protection portions of the complete circuit path are nodally diverse.

Nodal Diversity Desired—Specifies that node diversity is preferred, but if node diversity is not possible, CTC creates fiber-diverse paths for the path protection portion of the complete circuit path.

Link Diversity Only—Specifies that only fiber-diverse primary and alternate paths for path protection portions of the complete circuit path are needed. The paths might be node-diverse, but CTC does not check for node diversity.

Step 13If you selected Fully Protected Path in Step 11 and the circuit will be routed on a BLSR DRI or path protection DRI, click the Dual Ring Interconnect check box.

Step 14Click Next. In the Create area of the VT Matrix Optimization page, choose one of the following:

Create VT tunnel on transit nodes—This option is available if the DS-1 circuit passes through a node that does not have a VT tunnel, or if an existing VT tunnel is full. VT tunnels allow VT circuits to pass through ONS 15454s without consuming cross-connect card resources. VT tunnels can carry 28 VT1.5 circuits. In general, creating VT tunnels is a good idea if you are creating many VT circuits from the same source and destination. Refer to the Cisco ONS 15454 Reference Manual for more information.

Create VT aggregation point—This option is available if the DS-1 circuit source or destination is on an EC1, DS3, DS3E, DS3i-N-12, DS3/EC1-48, DS3XM-6, DS3XM-12, or OC-N port on a BLSR, 1+1, or unprotected node. VAPs collect DS-1s on an STS for handoff to non-ONS 15454 networks or equipment, such as an IOF, switch, or DACS. It allows VT1.5 circuits to be routed through the node using one STS connection on the cross-connect card matrix rather than multiple VT connections on the cross-connect card VT matrix. If you want to aggregate the DS-1 circuit you are creating with others onto an STS for transport outside the ONS 15454 network, choose one of the following:

– STS grooming node is source node, VT grooming node is destination node —Creates the VAP on the DS-1 circuit source node. This option is available only if the DS-1 circuit originates on an EC1, DS3, DS3E, DS3i-N-12, DS3XM-6, DS3XM-12, or OC-N card.

– STS grooming node is destination node, VT grooming node is source node —Creates the VAP on the DS-1 circuit destination node. This option is available only if the DS-1 circuit terminates on an EC1, DS3, DS3E, DS3i-N-12, DS3XM-6, DS3XM-12, or OC-N card.

None—Choose this option if you do not want to create a VT tunnel or a VAP. This is the only available option if CTC cannot create a VT tunnel or VAP.

Step 15Click Next. In the Route Review/Edit area, node icons appear for you to route the circuit manually. If you checked Dual Ring Interconnect for BLSR, continue with Step 16. If not, continue with Step 17.

All nodes in the DCC network appear on the network map. Circuit source and destination information appears under the source and destination nodes. To see a detailed view of the circuit, click Show Detailed Map. To rearrange a node icon, select the node, press Ctrl, then drag and drop the icon to the new location.

c. Port, STS, VT, or DS1—Choose the port, STS, VT, or DS-1 from the Port, STS, VT, or DS1 drop-down lists. The card you chose in Step b determines the fields that appear. See Table 6-2 for a list of options.

d. The routing preferences for the new drop match those of the original circuit. However, if the following options are available, you can modify them:

If the original circuit was routed on a protected path protection path, you can change the nodal diversity options: Nodal Diversity Required, Nodal Diversity Desired, or Link Diversity Only. See Step 12 for the option descriptions.

If the original circuit was not routed on a protected path, the Protection Channel Access option is available. See Step 11 for a description of the PCA option.

e. If you want to change the circuit state, choose the circuit state from the Target Circuit Admin State drop-down list. The state chosen applies to the entire circuit.

f. Check Apply to drop ports if you want to apply the state chosen in the Target Circuit Admin State to the circuit source and destination drops. For the requirements necessary to apply a service state to drop ports, refer to the Cisco ONS 15454 Reference Manual.

g. Click Finish. The new drop appears in the Drops list.

Step 24 If you need to create additional drops for the circuit, repeat Steps 22 and 23 to create the additional drops.

Step 25Click Close. The Circuits window appears.

Step 26 Verify that the new drops appear in the Destination column for the circuit you edited. If they do not appear, repeat Steps 5 through 25, making sure all options are provisioned correctly.

This procedure creates an automatically routed DS-3 or EC-1 circuit and also gives you the option of creating a circuit over a pair of portless transmultiplexing interfaces. CTC routes the circuit automatically based on circuit creation parameters and the software version.

Tools/Equipment

For portless transmultiplexing configurations, a DS3XM-12 must be installed on a node through which the circuit will be routed.

For VT2 circuits, the following cards must be installed at the circuit source and destination nodes: XC-VXC-10G and EC1.

Note This procedure requires the use of automatic routing. Automatic routing is not available if both the Automatic Circuit Routing NE default and the Network Circuit Automatic Routing Overridable NE default are set to FALSE. For a full description of these defaults see the “Network Element Defaults” appendix in the Cisco ONS 15454 Reference Manual.

Step 1 Complete the A60 Log into CTC at the node where you will create the circuit. If you are already logged in, continue with Step 2.

Step 2If you want to assign a name to the circuit source and destination ports before you create the circuit, complete the A314 Assign a Name to a Port. If not, continue with Step 3.

Step 3From the View menu, choose Go to Network View.

Step 4 Click the Circuits tab, then click Create.

Step 5 In the Circuit Creation dialog box, complete the following fields:

Circuit Type—Choose VT or STS. STS cross-connects will carry the DS-3 or EC-1 circuit across the ONS 15454 network.

Number of Circuits—Enter the number of DS-3 or EC-1 circuits that you want to create. The default is 1. If you are creating multiple circuits with sequential source and destination ports, you can use Auto-ranged to create the circuits automatically.

Auto-ranged—This box is automatically selected if you enter more than 1 in the Number of Circuits field. Leave selected if you are creating multiple DS-3 or EC-1 circuits with the same source and destination and you want CTC to create the circuits automatically. Uncheck the box if you do not want CTC to create sequential circuits automatically.

Name—Assign a name to the circuit. The name can be alphanumeric and up to 48 characters (including spaces). Circuit names should be 43 characters or less if you want the ability to create monitor circuits. If you leave the field blank, CTC assigns a default name to the circuit.

Size—For circuits on the DS3i-N-12 card, choose STS-3c. This sets a port group for Ports 1, 4, 7, and 10 using three ports at any given time. For VT2 circuits on the EC1 card, choose VT2. For all other circuits, choose STS-1.

Bidirectional—Leave checked for this circuit (default).

Create cross-connects only (TL1-like)—Check this box if you want to create one or more cross-connects to complete a signal path for TL1-generated circuits. If you check this box, VT tunnels and Ethergroup sources and destinations are unavailable.

State—Choose the administrative state to apply to all of the cross-connects in a circuit:

– IS—Puts the circuit cross-connects in the IS-NR service state.

– OOS,DSBLD—Puts the circuit cross-connects in the OOS-MA,DSBLD service state. Traffic is not passed on the circuit.

– IS,AINS—Puts the circuit cross-connects in the OOS-AU,AINS service state and suppresses alarms and conditions. When the connections receive a valid signal, the service state automatically changes to IS-NR.

– OOS,MT—Puts the circuit cross-connects in the OOS-MA,MT service state. The maintenance state does not interrupt traffic flow; it suppresses alarms and conditions and allows loopbacks to be performed on the circuit. Use OOS,MT for circuit testing or to suppress circuit alarms temporarily. Change the administrative state to IS; IS,AINS; or OOS,DSBLD when testing is complete. See the A230 Change a Circuit Service State.

For additional information about circuit service states, refer to the “Circuits and Tunnels” chapter in the Cisco ONS 5454 Reference Manual.

Apply to drop ports—Check this check box if you want to apply the administrative state chosen in the State field to the circuit source and destination ports. CTC applies the administrative state to the ports only if the circuit bandwidth is the same as the port bandwidth or, if the port bandwidth is larger than the circuit, the circuit must be the first circuit to use the port. If not, a Warning dialog box displays the ports where the administrative state could not be applied. If the check box is unchecked, CTC does not apply the administrative state to the source and destination ports.

Note If ports managed into the IS administrative state are not receiving signals, loss of signal alarms are generated and the port service state transitions to OOS-AU,FLT.

Protected Drops—Check this box if you want the circuit routed on protected drops only, that is, to ONS 15454 cards that are in 1:1, 1:N, 1+1, or optimized 1+1 protection. If you check this box, CTC provides only protected cards and ports as source and destination choices.

Using Required Nodes/Spans—Check this check box to specify nodes and spans to include or exclude in the CTC-generated circuit route.

Including nodes and spans for a circuit ensures that those nodes and spans are in the working path of the circuit (but not the protect path). Excluding nodes and spans ensures that the nodes and spans are not in the working or protect path of the circuit.

Review Route Before Creation—Check this check box to review and edit the circuit route before the circuit is created.

VT-DS3 Mapped Conversion—Check this check box to create a circuit using the portless transmultiplexing interface of the DS3XM-12 card.

Step 12To set the circuit path protection, complete one of the following:

To route the circuit on a protected path, leave Fully Protected Path checked and continue with Step 13. CTC creates a fully protected circuit route based on the path diversity option you choose. Fully protected paths might or might not have path protection path segments (with primary and alternate paths), and the path diversity options apply only to path protection path segments, if any exist.

Caution Circuits routed on BLSR protection channels are not protected and are preempted during BLSR switches.

Step 13If you selected Fully Protected Path in Step 12 and the circuit will be routed on a path protection configuration, choose one of the following:

Nodal Diversity Required—Ensures that the primary and alternate paths within path protection portions of the complete circuit path are nodally diverse.

Nodal Diversity Desired—Specifies that node diversity is preferred, but if node diversity is not possible, CTC creates fiber-diverse paths for the path protection portion of the complete circuit path.

Link Diversity Only—Specifies that only fiber-diverse primary and alternate paths for path protection portions of the complete circuit path are needed. The paths might be node-diverse, but CTC does not check for node diversity.

Step 14If you selected Fully Protected Path in Step 12 and the circuit will be routed on a BLSR DRI or path protection DRI, check the Dual Ring Interconnect check box.

DS3 Mapped STS—If applicable, choose Circuit Dest to indicate that the STS is the circuit destination, or Circuit Source to indicate that the STS is the circuit source.

Step 16If you checked Using Required Nodes/Spans in Step 11 or Dual Ring Interconnect for a path protection configuration in Step 14, complete the following substeps. If you checked Dual Ring Interconnect for a BLSR, skip this step and continue with Step 17. If you did not select any of these options, continue with Step 18.

a. In the Circuit Constraints for Automatic Routing area, click a node or span on the circuit map.

b. Click Include to include the node or span in the circuit. Click Exclude to exclude the node or span from the circuit. The order in which you choose included nodes and spans is the order in which the circuit is routed. Click spans twice to change the circuit direction.

c. Repeat Step b for each node or span you wish to include or exclude.

d. Review the circuit route. To change the circuit routing order, choose a node in the Required Nodes/Lines or Excluded Nodes Links lists and click the Up or Down buttons to change the circuit routing order. Click Remove to remove a node or span.

Step 18Click Next. If you are creating VT circuits, in the Create area of the VT Matrix Optimization page choose one of the following options. If not, continue with Step 18.

Create VT tunnel on transit nodes—This option is available if the DS-1 circuit passes through a node that does not have a VT tunnel, or if an existing VT tunnel is full. VT tunnels allow VT circuits to pass through ONS 15454s without consuming cross-connect card resources. VT tunnels can carry 28 VT1.5 circuits. In general, creating VT tunnels is a good idea if you are creating many VT circuits from the same source and destination. Refer to the Cisco ONS 15454 Reference Manual for more information.

Create VT aggregation point—This option is available if the DS-1 circuit source or destination is on an EC1, DS3, DS3E, DS3i-N-12, DS3/EC1-48, DS3XM-6, DS3XM-12, or OC-N port on a BLSR, 1+1, or unprotected node. VAPs collect DS-1s on an STS for handoff to non-ONS 15454 networks or equipment, such as an IOF, switch, or DACS. It allows VT1.5 circuits to be routed through the node using one STS connection on the cross-connect card matrix rather than multiple VT connections on the cross-connect card VT matrix. If you want to aggregate the DS-1 circuit you are creating with others onto an STS for transport outside the ONS 15454 network, choose one of the following:

– STS grooming node is source node, VT grooming node is destination node —Creates the VAP on the DS-1 circuit source node. This option is available only if the DS-1 circuit originates on an EC1, DS3, DS3E, DS3i-N-12, DS3/EC1-48, DS3XM-6, DS3XM-12, or OC-N card.

– STS grooming node is destination node, VT grooming node is source node —Creates the VAP on the DS-1 circuit destination node. This option is available only if the DS-1 circuit terminates on an EC1, DS3, DS3E, DS3i-N-12, DS3/EC1-48, DS3XM-6, DS3XM-12, or OC-N card.

None—Choose this option if you do not want to create a VT tunnel or a VAP. This is the only available option if CTC cannot create a VT tunnel or VAP.

Step 19Click Next. If you selected Review Route Before Creation in Step 11, complete the following substeps; otherwise, continue with Step 20.

a. Click Next.

b. Review the circuit route. To add or delete a circuit span, choose a node on the circuit route. Blue arrows show the circuit route. Green arrows indicate spans that you can add. Click a span arrowhead, then click Include to include the span or Remove to remove the span.

c. If the provisioned circuit does not reflect the routing and configuration you want, click Back to verify and change circuit information. If the circuit needs to be routed to a different path, see the A185 Create a Manually Routed DS-3 or EC-1 Circuit.

Step 20Click Finish. One of the following occurs if you entered more than 1 in the Number of Circuits field on the Circuit Creation dialog box:

If you chose Auto-ranged, CTC automatically creates the number of circuits entered in the Number of Circuits field. If auto-ranging cannot complete all the circuits, for example, because sequential ports are unavailable at the source or destination, a dialog box appears. Set the new source or destination for the remaining circuits, then click Finish to continue auto-ranging. After completing the circuits, the Circuits window appears.

If you did not choose Auto-ranged, the Circuit Creation dialog box appears so you can create the remaining circuits. Repeat Steps 5 through 19 for each additional circuit. After completing the circuits, the Circuits window appears.

Step 21In the Circuits window, verify that the circuits you just created appear in the circuits list.

Number of Circuits—Enter the number of DS-3 or EC-1 circuits that you want to create. The default is 1.

Auto-ranged—(Automatically routed circuits only) If you entered more than 1 in the Number of Circuits field, uncheck this box. (The box is unavailable if only one circuit is entered in the Number of Circuits field.)

Name—Assign a name to the circuit. The name can be alphanumeric and up to 48 characters (including spaces). Circuit names should be 43 characters or less if you want the ability to create monitor circuits. If you leave this field blank, CTC assigns a default name to the circuit.

Size—For circuits on the DS3i-N-12 card, choose STS-3c. This sets a port group for Ports 1, 4, 7, and 10 using three ports at any given time. For VT2 circuits on the EC1 card, choose VT2. For all other circuits, choose STS-1.

Bidirectional—Leave this field checked (default).

Create cross-connects only (TL1-like)—Check this box if you want to create one or more cross-connects to complete a signal path for TL1-generated circuits. If you check this box, VT tunnels and Ethergroup sources and destinations are unavailable.

State—Choose the administrative state to apply to all of the cross-connects in a circuit:

– IS—Puts the circuit cross-connects in the IS-NR service state.

– OOS,DSBLD—Puts the circuit cross-connects in the OOS-MA,DSBLD service state. Traffic is not passed on the circuit.

– IS,AINS—Puts the circuit cross-connects in the OOS-AU,AINS service state and suppresses alarms and conditions. When the connections receive a valid signal, the service state automatically changes to IS-NR.

– OOS,MT—Puts the circuit cross-connects in the OOS-MA,MT service state. The maintenance state does not interrupt traffic flow; it suppresses alarms and conditions and allows loopbacks to be performed on the circuit. Use OOS,MT for circuit testing or to suppress circuit alarms temporarily. Change the administrative state to IS; IS,AINS; or OOS,DSBLD when testing is complete. See the A230 Change a Circuit Service State.

For additional information about circuit service states, refer to the “Circuits and Tunnels” chapter in the Cisco ONS 15454 Reference Manual.

Apply to drop ports—Check this check box if you want to apply the administrative state chosen in the State field to the circuit source and destination ports. CTC applies the administrative state to the ports only if the circuit bandwidth is the same as the port bandwidth or, if the port bandwidth is larger than the circuit, the circuit must be the first circuit to use the port. If not, a Warning dialog box displays the ports where the administrative state could not be applied. If the check box is unchecked, CTC does not apply the administrative state to the source and destination ports.

Note If ports managed into the IS administrative state are not receiving signals, loss of signal alarms are generated and the port service state transitions to OOS-AU,FLT.

Protected Drops—Check this check box if you want the circuit routed to protect drops only, that is, to ONS 15454 cards that are in 1:1, 1:N, 1+1, or optimized 1+1 protection. If you check this check box, CTC provides only protected cards as source and destination choices.

Step 11 In the Circuit Routing Preferences area (Figure 6-4), uncheck Route Automatically. When Route Automatically is not selected, the Using Required Nodes/Spans, Review Route Before Circuit Creation, and VT-DS3 Mapped Conversion check boxes are unavailable.

Step 12To set the circuit path protection, complete one of the following:

To route the circuit on a protected path, leave Fully Protected Path checked and continue with Step 13. Fully protected paths might or might not have path protection path segments (with primary and alternate paths), and the path diversity options apply only to path protection path segments, if any exist.

Caution Circuits routed on BLSR protection channels are not protected and are preempted during BLSR switches.

Step 13If you selected Fully Protected Path in Step 12 and the circuit will be routed on a path protection configuration, choose one of the following:

Nodal Diversity Required—Ensures that the primary and alternate paths within the path protection portions of the complete circuit path are nodally diverse.

Nodal Diversity Desired—Specifies that node diversity is preferred, but if node diversity is not possible, CTC creates fiber-diverse paths for the path protection portion of the complete circuit path.

Link Diversity Only—Specifies that only fiber-diverse primary and alternate paths for path protection portions of the complete circuit path are needed. The paths might be node-diverse, but CTC does not check for node diversity.

Step 14 If you selected Fully Protected Path in Step 12 and the circuit will be routed on a path protection DRI or BLSR DRI, click the Dual Ring Interconnect check box.

Step 15 Click Next. In the Route Review/Edit area, node icons appear for you to route the circuit manually. If you checked Dual Ring Interconnect for BLSR, continue with Step 16. If not, continue with Step 17.

Step 17In the Route Review and Edit area, node icons appear so you can route the circuit manually. The green arrows pointing from the selected node to other network nodes indicate spans that are available for routing the circuit.

Step 20 If you entered more than 1 in the Number of Circuits field on the Circuit Creation dialog box, the Circuit Creation dialog box appears so you can create the remaining circuits. Repeat Steps 5 through 19 for each additional circuit.

Step 21 When all the circuits are created, the main Circuits window appears. Verify that the circuits you created appear in the window.

Name—Assign a name to the circuit. The name can be alphanumeric and up to 48 characters (including spaces). Circuit names should be 43 characters or less if you want the ability to create monitor circuits. If you leave the field blank, CTC assigns a default name to the circuit.

Size—For circuits on the DS3i-N-12 card, choose STS-3c. For VT2 circuits on the EC1 card, choose VT2. For all other circuits, choose STS-1.

Bidirectional—Uncheck for this circuit.

Create cross-connects only (TL1-like)—Check this box if you want to create one or more cross-connects to complete a signal path for TL1-generated circuits. If you check this box, VT tunnels and Ethergroup sources and destinations are unavailable.

Step 10 Click Next.

Step 11 In the Circuit Destination area, choose the node where the VT tunnel will terminate from the Node drop-down list.

Step 14 Click Next. In the Route Review and Edit area, node icons appear so you can route the tunnel. The circuit source node is selected. Green arrows pointing from the source node to other network nodes indicate spans that are available for routing the tunnel.

Step 16 Verify that the tunnel you just created appears in the circuits list. VT tunnels are identified by VTT in the Type column.

Stop. You have completed this procedure.

NTP-A187 Create a VT Aggregation Point

Purpose

This procedure creates a VT aggregation point (VAP). VAPs allow multiple DS-1 (VT1.5) circuits to be aggregated on a single STS on an OC-N, EC1, DS3, DS3E, DS3/EC1-48, DS3XM-6, or DS3XM-12 card. VAPs allow multiple VT1.5 circuits to pass through cross-connect cards without utilizing resources on the cross-connect card VT matrix. You also have the option to route the circuit through a portless transmultiplexing interface.

Tools/Equipment

For portless transmultiplexing configurations, a DS3XM-12 card must be installed on a node in the network.

Note This procedure requires the use of automatic routing. Automatic routing is not available if both the Automatic Circuit Routing NE default and the Network Circuit Automatic Routing Overridable NE default are set to FALSE. For a full description of these defaults see the “Network Element Defaults” appendix in the Cisco ONS 15454 Reference Manual.

Note VT aggregation points can be created for circuits on BLSR, 1+1, or unprotected nodes. They cannot be created for circuits on path protection nodes.

Note The maximum number of VAPs that you can create depends on the node protection topology and number of VT1.5 circuits that terminate on the node. Assuming that no other VT1.5 circuits terminate at the node, the maximum number of VAPs that you can terminate at one node is 8 for 1+1 protection and 12 for BLSR protection.

Step 1 Complete the A60 Log into CTC at the node where you will create the VT aggregation point. If you are already logged in, continue with Step 2.

Step 2If you want to assign a name to the tunnel source and destination ports before you create the circuit, complete the A314 Assign a Name to a Port. If not, continue with Step 3.

Name—Assign a name to the VT aggregation point. The name can be alphanumeric and up to 48 characters (including spaces). Circuit names should be 43 characters or less if you want the ability to create monitor circuits. If you leave the field blank, CTC assigns a default name to the VAP.

Size—Unavailable for VAPs.

Bidirectional—Unavailable for VAPs.

State—Choose the administrative state to apply to all of the cross-connects in a circuit:

– IS—Puts the circuit cross-connects in the IS-NR service state.

– OOS,DSBLD—Puts the circuit cross-connects in the OOS-MA,DSBLD service state. Traffic is not passed on the circuit.

– IS,AINS—Puts the circuit cross-connects in the OOS-AU,AINS service state and suppresses alarms and conditions. When the connections receive a valid signal, the service state automatically changes to IS-NR.

– OOS,MT—Puts the circuit cross-connects in the OOS-MA,MT service state. The maintenance state does not interrupt traffic flow; it suppresses alarms and conditions and allows loopbacks to be performed on the circuit. Use OOS,MT for circuit testing or to suppress circuit alarms temporarily. Change the administrative state to IS; IS,AINS; or OOS,DSBLD when testing is complete. See the A230 Change a Circuit Service State.

NTP-A135 Test Electrical Circuits

Purpose

This procedures tests DS-1 and DS-3 or EC-1 circuits.

Tools/Equipment

A test set and all appropriate cables

Prerequisite Procedures

This procedure assumes that you completed a facility loopback tests on the fibers and cables from the source and destination ONS 15454s to the digital signal cross-connect (DSX), and that you created a circuit using one of the following procedures:

Step 1Complete the A60 Log into CTC at the node where you want to test the electrical circuits. If you are already logged in, continue with Step 2.

Step 2From the View menu, choose Go to Network View.

Step 3 Click the Circuits tab.

Step 4 Complete the A230 Change a Circuit Service State to set the circuit and circuit ports to the maintenance service state (OOS-MA,MT). Take note of the original state because you will return the circuit to that state later.

Step 5 Set the source and destination DS1 or DS3 card line length:

a.In network view, double-click the source node.

b. Double-click the circuit source card and click the Provisioning > Line tabs.

c. From the circuit source port Line Length drop-down list, choose the line length for the distance (in feet) between the DSX (if used) or circuit termination point and the source ONS 15454.

a. Verify the integrity of the loopback cable by looping the test set transmit (Tx) connector to the test set receive (Rx) connector. If the test set does not run error-free, check the cable for damage and check the test set to make sure it is set up correctly before going to Step b.

b.Attach the loopback cable to the port you are testing. Connect the Tx connector to the Rx connector of the port.

Step 7 Attach loopback cables to the circuit source node:

a. Verify the integrity of loopback cable by looping the test set Tx connector to the test set Rx connector. If the test set does not run error-free, check the cable for damage and check the test set to make sure it is set up correctly before going to Step b.

b.Attach the loopback cable to the port you are testing. Connect the test set to the circuit source port. Connect the Tx port of the test set to the circuit Rx port, and the test set Rx port to the circuit Tx port.

Step 8Configure the test set for the ONS 15454 card that is the source of the circuit you are testing:

DS-1—If you are testing an unmultiplexed DS-1, you must have a DSX-1 page or a direct DS-1 interface into the ONS 15454. Set the test set for DS-1. For information about configuring your test set, consult your test set user guide.

DS-3—If you are testing a clear channel DS-3, you must have a DSX-3 page or a direct DS-3 interface into the ONS 15454. Set the test set for clear channel DS-3. For information about configuring your test set, consult your test set user guide.

DS3XM—If you are testing a DS-1 circuit on a DS3XM-6 or DS3XM-12 card you must have a DSX-3 page or a direct DS-3 interface to the ONS 15454. Set the test set for a multiplexed DS-3. After you choose multiplexed DS-3, choose the DS-1 to test on the multiplexed DS-3. For information about configuring your test set, consult your test set user guide.

EC-1—If you are testing a DS-1 on an EC1 card, you must have a DSX-3 page or a direct DS-3 interface to the ONS 15454. Set the test set for an STS-1. After you choose STS-1, choose the DS-1 to test the STS-1. For information about configuring your test set, consult your test set user guide.

Step 9 Verify that the test set shows a clean signal. If a clean signal does not appear, repeat Steps 2 through 8 to make sure the test set and cabling is configured correctly.

Step 10 Inject errors from the test set. Verify that the errors appear at the source and destination nodes.

Note This procedure requires the use of automatic routing. Automatic routing is not available if both the Automatic Circuit Routing NE default and the Network Circuit Automatic Routing Overridable NE default are set to FALSE. For a full description of these defaults see the “Network Element Defaults” appendix in the Cisco ONS 15454 Reference Manual.

Step 1 Complete the A60 Log into CTC at the node where you will create the circuit. If you are already logged in, continue with Step 2.

Step 2If you want to assign a name to the tunnel source and destination ports before you create the circuit, complete the A314 Assign a Name to a Port. If not, continue with Step 3.

Step 3Complete the following as necessary (you can provision Ethernet or packet-over-SONET [POS] ports before or after the STS circuit is created):

Number of Circuits—Enter the number of optical circuits that you want to create. The default is 1. If you are creating multiple circuits with the same source and destination, you can use auto-ranging to create the circuits automatically.

Auto-ranged—This check box is automatically selected when you enter more than 1 in the Number of Circuits field. Leave this check box selected if you are creating multiple optical circuits with the same source and destination and you want CTC to create the circuits automatically. Uncheck the box if you do not want CTC to create the circuits automatically.

Name—Assign a name to the circuit. The name can be alphanumeric and up to 48 characters (including spaces). Circuit names should be 43 characters or less if you want the ability to create monitor circuits. If you leave the field blank, CTC assigns a default name to the circuit.

Note Restrictions apply to provisioning multiple circuits on a G-Series card when one of the circuit sizes provisioned is STS-24c. Refer to the Cisco ONS 15454 Reference Manual for complete information.

Bidirectional—Leave checked for this circuit (default).

Create cross-connects only (TL1-like)—Check this box if you want to create one or more cross-connects to complete a signal path for TL1-generated circuits. If you check this box, VT tunnels and Ethergroup sources and destinations are unavailable.

State—Choose the administrative state to apply to all of the cross-connects in a circuit:

– IS—Puts the circuit cross-connects in the IS-NR service state.

– OOS,DSBLD—Puts the circuit cross-connects in the OOS-MA,DSBLD service state. Traffic is not passed on the circuit.

– IS,AINS—Puts the circuit cross-connects in the OOS-AU,AINS service state and suppresses alarms and conditions. When the connections receive a valid signal, the service state automatically changes to IS-NR.

– OOS,MT—Puts the circuit cross-connects in the OOS-MA,MT service state. The maintenance state does not interrupt traffic flow; it suppresses alarms and conditions and allows loopbacks to be performed on the circuit. Use OOS,MT for circuit testing or to suppress circuit alarms temporarily. Change the administrative state to IS; IS,AINS; or OOS,DSBLD when testing is complete. See the A230 Change a Circuit Service State.

For additional information about circuit service states, refer to the “Circuits and Tunnels” chapter in the Cisco ONS 15454 Reference Manual.

Apply to drop ports—Check this check box if you want to apply the administrative state chosen in the State field to the circuit source and destination ports. CTC applies the administrative state to the ports only if the circuit bandwidth is the same as the port bandwidth or, if the port bandwidth is larger than the circuit, the circuit must be the first circuit to use the port. If not, a Warning dialog box displays the ports where the administrative state could not be applied. If the check box is unchecked, CTC does not apply the administrative state to the source and destination ports.

Note If ports managed into the IS administrative state are not receiving signals, loss of signal alarms are generated and the port service state transitions to OOS-AU,FLT.

Protected Drops—Check this check box if you want the circuit routed to protected drops only, that is, to ONS 15454 cards that are in 1:1, 1:N, 1+1, or optimized 1+1 protection. If you check this check box, CTC provides only protected cards as source and destination choices.

Using Required Nodes/Spans—Check this check box to specify nodes and spans to include or exclude in the CTC-generated circuit route.

Including nodes and spans for a circuit ensures that those nodes and spans are in the working path of the circuit (but not the protect path). Excluding nodes and spans ensures that the nodes and spans are not in the working or protect path of the circuit.

Review Route Before Creation—Check this check box to review and edit the circuit route before the circuit is created.

VT-DS3 Mapped Conversion—Check this check box to create a circuit using the portless transmultiplexing interface of the DS3XM-12 card.

Step 13To set the circuit path protection, complete one of the following:

To route the circuit on a protected path, leave Fully Protected Path checked and continue with Step 14. CTC creates a fully protected circuit route based on the path diversity option you choose. Fully protected paths might or might not have path protection path segments (with primary and alternate paths), and the path diversity options apply only to path protection path segments, if any exist.

Step 14If you selected Fully Protected Path in Step 13 and the circuit will be routed on a path protection configuration, choose one of the following:

Nodal Diversity Required—Ensures that the primary and alternate paths within path protection portions of the complete circuit path are nodally diverse.

Nodal Diversity Desired—Specifies that node diversity is preferred, but if node diversity is not possible, CTC creates fiber-diverse paths for the path protection portion of the complete circuit path.

Link Diversity Only—Specifies that only fiber-diverse primary and alternate paths for path protection portions of the complete circuit path are needed. The paths might be node-diverse, but CTC does not check for node diversity.

Step 15If you selected Fully Protected Path in Step 13 and the circuit will be routed on a BLSR DRI or path protection DRI, check the Dual Ring Interconnect check box.

Step 16Click Next.

Step 17 If you selected VT-DS3 Mapped Conversion in Step 12, complete the following substeps; otherwise, continue with Step 18:

Step 21Click Finish. One of the following results occurs if you entered more than 1 in the Number of Circuits field on the Circuit Creation dialog box:

If you chose Auto-ranged, CTC automatically creates the number of circuits entered in the Number of Circuits field. If auto-ranging cannot complete all the circuits, for example, because sequential ports are unavailable on the source or destination, a dialog box appears. Set the new source or destination for the remaining circuits, then click Finish to continue auto-ranging. After completing the circuits, the Circuits window appears.

If you did not choose Auto-ranged, the Circuit Creation dialog box appears so you can create the remaining circuits. Repeat Steps 6 through 20 for each additional circuit. After completing the circuits, the Circuits window appears.

Step 22 In the Circuits window, verify that the circuits you created appear in the circuits list.

Step 23Complete the following as necessary. Skip this step if you built a test circuit.

Number of Circuits—Enter the number of optical circuits that you want to create. The default is 1.

Auto-ranged—(Automatically routed circuits only) If you entered more than 1 in the Number of Circuits field, uncheck this box. (The box is unavailable if only one circuit is entered in the Number of Circuits field.)

Step 7 Click Next.

Step 8 Define circuit attributes:

Name—Assign a name to the circuit. The name can be alphanumeric and up to 48 characters (including spaces). Circuit names should be 43 characters or less if you want the ability to create monitor circuits. If you leave the field blank, CTC assigns a default name to the circuit.

Note Restrictions apply to provisioning multiple circuits on a G-Series card when one of the circuit sizes provisioned is STS-24c. Refer to the Cisco ONS 15454 Reference Manual for complete information.

Bidirectional—Leave checked for this circuit (default).

Create cross-connects only (TL1-like)—Check this box if you want to create one or more cross-connects to complete a signal path for TL1-generated circuits. If you check this box, VT tunnels and Ethergroup sources and destinations are unavailable.

State—Choose the administrative state to apply to all of the cross-connects in a circuit:

– OOS,MT—Puts the circuit cross-connects in the OOS-MA,MT service state. The maintenance state does not interrupt traffic flow; it suppresses alarms and conditions and allows loopbacks to be performed on the circuit. Use OOS,MT for circuit testing or to suppress circuit alarms temporarily. Change the administrative state to IS; IS,AINS; or OOS,DSBLD when testing is complete. See the A230 Change a Circuit Service State.

For additional information about circuit service states, refer to the “Circuits and Tunnels” chapter in the Cisco ONS 15454 Reference Manual.

Apply to drop ports—Check this check box if you want to apply the administrative state chosen in the State field to the circuit source and destination ports. CTC applies the administrative state to the ports only if the circuit bandwidth is the same as the port bandwidth or, if the port bandwidth is larger than the circuit, the circuit must be the first circuit to use the port. If not, a Warning dialog box displays the ports where the administrative state could not be applied. If the check box is unchecked, CTC does not apply the administrative state to the source and destination ports.

Note If ports managed into the IS administrative state are not receiving signals, loss of signal alarms are generated and the port service state transitions to OOS-AU,FLT.

Protected Drops—Check this check box if you want the circuit routed to protect drops only, that is, to ONS 15454 cards that are in 1:1, 1:N, 1+1, or optimized 1+1 protection. If you check this check box, CTC provides only protected cards as source and destination choices.

Caution Circuits routed on BLSR protection channels are not protected and are preempted during BLSR switches.

Step 14If you selected Fully Protected Path in Step 13 and the circuit will be routed on a path protection configuration, choose one of the following:

Nodal Diversity Required—Ensures that the primary and alternate paths within the path protection portions of the complete circuit path are nodally diverse.

Nodal Diversity Desired—Specifies that node diversity is preferred, but if node diversity is not possible, CTC creates fiber-diverse paths for the path protection portion of the complete circuit path.

Link Diversity Only—Specifies that only fiber-diverse primary and alternate paths for path protection portions of the complete circuit path are needed. The paths might be node-diverse, but CTC does not check for node diversity.

Step 15If you selected Fully Protected Path in Step 13 and the circuit will be routed on a BLSR DRI or path protection DRI, check the Dual Ring Interconnect check box.

Step 16Click Next. In the Route Review/Edit area, node icons appear for you to route the circuit manually. If you checked Dual Ring Interconnect for BLSR, continue with Step 17. If not, continue with Step 18.

Step 19Click Finish. If the path does not meet the specified path diversity requirement, CTC displays an error message and allows you to change the circuit path. If you entered more than 1 in the Number of Circuits field on the Circuit Creation dialog box, the Circuit Creation dialog box appears after the circuit is created so you can create the remaining circuits. Repeat Steps 6 through 18 for each additional circuit.

Step 20 When all the circuits are created, the main Circuits window appears. Verify that the circuits you created appear in the window.

Step 21 Complete the following as necessary. Skip this step if you built a test circuit.

Name—Assign a name to the circuit. The name can be alphanumeric and up to 48 characters (including spaces). Circuit names should be 43 characters or less if you want the ability to create monitor circuits. If you leave the field blank, CTC assigns a default name to the circuit.

Create cross-connects only (TL1-like)—Check this box if you want to create one or more cross-connects to complete a signal path for TL1-generated circuits. If you check this box, VT tunnels and Ethergroup sources and destinations are unavailable.

State—Choose the administrative state to apply to all of the cross-connects in a circuit:

– IS—Puts the circuit cross-connects in the IS-NR service state.

– OOS,DSBLD—Puts the circuit cross-connects in the OOS-MA,DSBLD service state. Traffic is not passed on the circuit.

– IS,AINS—Puts the circuit cross-connects in the OOS-AU,AINS service state and suppresses alarms and conditions. When the connections receive a valid signal, the service state automatically changes to IS-NR.

– OOS,MT—Puts the circuit cross-connects in the OOS-MA,MT service state. The maintenance state does not interrupt traffic flow; it suppresses alarms and conditions and allows loopbacks to be performed on the circuit. Use OOS,MT for circuit testing or to suppress circuit alarms temporarily. Change the administrative state to IS; IS,AINS; or OOS,DSBLD when testing is complete. See the A230 Change a Circuit Service State.

For additional information about circuit service states, refer to the “Circuits and Tunnels” chapter in the Cisco ONS 15454 Reference Manual.

Apply to drop ports—Check this check box if you want to apply the administrative state chosen in the State field to the circuit source and destination ports. CTC applies the administrative state to the ports only if the circuit bandwidth is the same as the port bandwidth or, if the port bandwidth is larger than the circuit, the circuit must be the first circuit to use the port. If not, a Warning dialog box displays the ports where the administrative state could not be applied. If the check box is unchecked, CTC does not apply the administrative state to the source and destination ports.

Note If ports managed into the IS administrative state are not receiving signals, loss of signal alarms are generated and the port service state transitions to OOS-AU,FLT.

Protected Drops—Check this check box if you want the circuit routed to protect drops only, that is, to ONS 15454 cards that are in 1:1, 1:N, 1+1, or optimized 1+1 protection. If you check this check box, CTC provides only protected cards as source and destination choices.

Step 11 Uncheck Route Automatically. When Route Automatically is not selected, the Using Required Nodes/Spans and Review Route Before Circuit Creation check boxes are unavailable.

Step 12To set the circuit path protection, complete one of the following:

To route the circuit on a protected path, leave Fully Protected Path checked and continue with Step 13. Fully protected paths might or might not have path protection path segments (with primary and alternate paths), and the path diversity options apply only to path protection path segments, if any exist.

Caution Circuits routed on BLSR protection channels are not protected and are preempted during BLSR switches.

Step 13If you selected Fully Protected Path in Step 12 and the circuit will be routed on a path protection configuration, choose one of the following:

Nodal Diversity Required—Ensures that the primary and alternate paths within the path protection portions of the complete circuit path are nodally diverse.

Nodal Diversity Desired—Specifies that node diversity is preferred, but if node diversity is not possible, CTC creates fiber-diverse paths for the path protection portion of the complete circuit path.

Link Diversity Only—Specifies that only fiber-diverse primary and alternate paths for path protection portions of the complete circuit path are needed. The paths might be node-diverse, but CTC does not check for node diversity.

Note For manually routed circuits, CTC checks your manually provisioned path against the path diversity option you choose. If the path does not meet the path diversity requirement that is specified, CTC displays an error message.

Step 14If you selected Fully Protected Path in Step 12 and the circuit will be routed on a BLSR DRI or path protection DRI, check the Dual Ring Interconnect check box.

Step 15Click Next. In the Route Review/Edit area, node icons appear for you to route the circuit manually. If you checked Dual Ring Interconnect for BLSR, continue with Step 16. If not, continue with Step 17.

You can rearrange the node icons by pressing Ctrl while you drag and drop the icon to the new location.

c. Port, STS—Choose the port and/or STS from the Port and STS drop-down lists. The choice in these menus depends on the card selected in Step b. See Table 6-2 for a list of options.

d. The routing preferences for the new drop match those of the original circuit. However, if the following options are available, you can modify them:

If the original circuit was routed on a protected path protection path, you can change the nodal diversity options: Nodal Diversity Required, Nodal Diversity Desired, or Link Diversity Only. See Step 13 for option descriptions.

If the original circuit was not routed on a protected path, the Protection Channel Access option is available. See Step 12 for a description of the PCA option.

e. If you want to change the circuit state, choose the circuit state from the Target Circuit Admin State drop-down list. The state chosen applies to the entire circuit.

f. Check Apply to drop ports if you want to apply the state chosen in the Target Circuit Admin State to the circuit source and destination drops. For the requirements necessary to apply a service state to drop ports, refer to the Cisco ONS 15454 Reference Manual.

g. Click Finish. The new drop appears in the Drops list.

Step 24 If you need to create additional drops on the circuit, repeat Steps 21 through 23.

– IS—Puts the circuit cross-connects in the IS-NR service state.

– OOS,DSBLD—Puts the circuit cross-connects in the OOS-MA,DSBLD service state. Traffic is not passed on the circuit.

– IS,AINS—Puts the circuit cross-connects in the OOS-AU,AINS service state and suppresses alarms and conditions. When the connections receive a valid signal, the service state automatically changes to IS-NR.

– OOS,MT—Puts the circuit cross-connects in the OOS-MA,MT service state. The maintenance state does not interrupt traffic flow; it suppresses alarms and conditions and allows loopbacks to be performed on the circuit. Use OOS,MT for circuit testing or to suppress circuit alarms temporarily. Change the administrative state to IS; IS,AINS; or OOS,DSBLD when testing is complete. See the A230 Change a Circuit Service State.

For additional information about circuit service states, refer to the “Circuits and Tunnels” chapter in the Cisco ONS 15454 Reference Manual.

Apply to drop ports—Check this check box if you want to apply the administrative state chosen in the State field to the circuit source and destination ports. CTC applies the administrative state to the ports only if the circuit bandwidth is the same as the port bandwidth or, if the port bandwidth is larger than the circuit, the circuit must be the first circuit to use the port. If not, a Warning dialog box displays the ports where the administrative state could not be applied. If the check box is unchecked, CTC does not apply the administrative state to the source and destination ports.

Note If ports managed into the IS administrative state are not receiving signals, loss of signal alarms are generated and the port service state transitions to OOS-AU,FLT.

Step 10Click Finish. One of the following results occurs if you entered more than 1 in the Number of Circuits field on the Circuit Creation dialog box:

If you chose Auto-ranged, CTC automatically creates the number of circuits entered in the Number of Circuits field. If auto-ranging cannot complete all the circuits, for example, because sequential ports are unavailable at the source or destination, a dialog box appears. Set the new source or destination for the remaining circuits, then click Finish to continue auto-ranging. After completing the circuits, the Circuits window appears.

If you did not choose Auto-ranged, the Circuit Creation dialog box appears so you can create the remaining circuits. Repeat Steps 5 through 9 for each additional circuit. After completing the circuits, the Circuits window appears.

Step 11 In the Circuits window, verify that the new circuits appear in the circuits list.

Number of Circuits—Enter the number of circuits that you want to create. The default is 1.

Auto-ranged—Uncheck this check box; it is automatically selected if you enter more than 1 in the Number of Circuits field.

Step 6 Click Next.

Step 7 Define the circuit attributes:

Name—Assign a name to the circuit. The name can be alphanumeric and up to 48 characters (including spaces). Circuit names should be 43 characters or less if you want the ability to create monitor circuits. If you leave the field blank, CTC assigns a default name to the circuit.

Create cross-connects only (TL1-like)—Check this box if you want to create one or more cross-connects to complete a signal path for TL1-generated circuits. If you check this box, VT tunnels and Ethergroup sources and destinations are unavailable.

State—Choose the administrative state to apply to all of the cross-connects in a circuit:

– IS—Puts the circuit cross-connects in the IS-NR service state.

– OOS,DSBLD—Puts the circuit cross-connects in the OOS-MA,DSBLD service state. Traffic is not passed on the circuit.

– IS,AINS—Puts the circuit cross-connects in the OOS-AU,AINS service state and suppresses alarms and conditions. When the connections receive a valid signal, the service state automatically changes to IS-NR.

– OOS,MT—Puts the circuit cross-connects in the OOS-MA,MT service state. The maintenance state does not interrupt traffic flow; it suppresses alarms and conditions and allows loopbacks to be performed on the circuit. Use OOS,MT for circuit testing or to suppress circuit alarms temporarily. Change the administrative state to IS; IS,AINS; or OOS,DSBLD when testing is complete. See the A230 Change a Circuit Service State.

For additional information about circuit service states, refer to the “Circuits and Tunnels” chapter in the Cisco ONS 15454 Reference Manual.

Apply to drop ports—Check this check box if you want to apply the administrative state chosen in the State field to the circuit source and destination ports. CTC applies the administrative state to the ports only if the circuit bandwidth is the same as the port bandwidth or, if the port bandwidth is larger than the circuit, the circuit must be the first circuit to use the port. If not, a Warning dialog box displays the ports where the administrative state could not be applied. If the check box is unchecked, CTC does not apply the administrative state to the source and destination ports.

Note If ports managed into the IS administrative state are not receiving signals, loss of signal alarms are generated and the port service state transitions to OOS-AU,FLT.

Step 11Click Finish. One of the following results occurs if you entered more than 1 in the Number of Circuits field on the Circuit Creation dialog box:

If you chose Auto-ranged, CTC automatically creates the number of circuits entered in the Number of Circuits field. If auto-ranging cannot complete all the circuits, for example, because sequential ports are unavailable at the source or destination, a dialog box appears. Set the new source or destination for the remaining circuits, then click Finish to continue auto-ranging. After completing the circuits, the Circuits window appears.

If you did not choose Auto-ranged, the Circuit Creation dialog box appears so you can create the remaining circuits. Repeat Steps 5 through 10 for each additional circuit. After completing the circuits, the Circuits window appears.

Step 12 In the Circuits window, verify that the new circuits appear in the circuits list.

Note This procedure requires the use of automatic routing. Automatic routing is not available if both the Automatic Circuit Routing NE default and the Network Circuit Automatic Routing Overridable NE default are set to FALSE. For a full description of these defaults see the “Network Element Defaults” appendix in the Cisco ONS 15454 Reference Manual.

Step 1 Complete the A60 Log into CTC at the node where you will create the EtherSwitch circuit. If you are already logged in, continue with Step 2.

Step 2If the network is already using a high number of VLANs, complete the A99 Determine Available VLANs to verify that sufficient VLAN capacity is available. (You will create a VLAN during each circuit creation task.)

Step 3 If enough VLANs are not available, complete the A335 Delete VLANs to free space.

Step 4 Verify that the circuit source and destination Ethernet cards are provisioned for the mode of the circuit that you will create, either multicard or single-card. See the A246 Provision E-Series Ethernet Card Mode.

Name—Assign a name to the circuit. The name can be alphanumeric and up to 48 characters (including spaces). Circuit names should be 43 characters or less if you want the ability to create monitor circuits. If you leave the field blank, CTC assigns a default name to the circuit.

Caution Layer 1 SONET protection does not extend to multicard EtherSwitch circuits on path protection configurations.
Caution A TCC2/TCC2P card reset disrupts single-card and multicard EtherSwitch circuits for 45 seconds to two minutes.
During this time, a spanning tree topology is created by the newly activated TCC2/TCC2P card.

Step 12 Click Next.

Step 13 Provision the circuit source:

a. From the Node drop-down list, choose one of the EtherSwitch circuit endpoint nodes. (Either end node can be the EtherSwitch circuit source.)

b. From the Slot drop-down list, choose one of the following:

If you are building a multicard EtherSwitch circuit, choose Ethergroup.

If you are building a single-card EtherSwitch circuit, choose the Ethernet card where you enabled the single-card EtherSwitch.

Step 14 Click Next.

Step 15 Provision the circuit destination:

a. From the Node drop-down list, choose the second EtherSwitch circuit endpoint node.

b. From the Slot drop-down list, choose one of the following:

If you are building a multicard EtherSwitch circuit, choose Ethergroup.

If you are building a single-card EtherSwitch circuit, choose the Ethernet card where you enabled the single-card EtherSwitch.

Tip You can also add VLANs in network view by choosing Tools > Manage VLANs. In the All VLANs dialog box, click the Create button to open the Define New VLAN dialog box.

Step 18 In the Define New VLAN dialog box, complete the following:

VLAN Name—Assign an easily identifiable name to your VLAN.

VLAN ID—Assign a VLAN ID. The VLAN ID should be the next available number between 2 and 4093 that is not already assigned to an existing VLAN. Each ONS 15454 network supports a maximum of 509 user-provisionable VLANs.

Topology Host—Choose the node to serve as the topology host from the drop-down list.

Step 19 Click OK.

Step 20In the Circuit VLAN Selection area, highlight the VLAN name and click the arrow button (>>) to move the available VLANs to the Circuit VLANs column.

Step 21 If you are building a single-card EtherSwitch circuit and want to disable spanning tree protection on this circuit, uncheck the Enable Spanning Tree check box and click OK in the Disabling Spanning Tree dialog box. The Enable Spanning Tree box remains checked or unchecked for the creation of the next single-card, point-to-point Ethernet circuit.

Caution Disabling spanning-tree protection increases the likelihood of logic loops on an Ethernet network.
Caution Turning off spanning tree on a circuit-by-circuit basis means that the ONS 15454 is no longer protecting the Ethernet circuit and that the circuit must be protected by another mechanism in the Ethernet network.
Caution Multiple circuits with spanning tree protection enabled incur blocking if the circuits traverse the same E-Series card and use the same VLAN.

NoteSpanning-tree rules prevent users from creating new circuits or modifying existing circuits if the circuits do not meet certain VLAN assignment constraints. If the VLAN set of the new circuit overlaps existing circuits, the same spanning-tree instance is used for all circuits. If the VLAN set of the new circuit overlaps with VLAN sets of existing circuits with different spanning-tree instances, the VLAN assignment fails. Cisco recommends that you plan VLAN assignments so that circuits with larger VLAN sets and a higher chance of overlap are added first. This means that if a circuit with an overlapping VLAN set is added, it collapses into the same spanning tree. To view circuits mapped to a spanning tree and their VLAN assignments, see the A430 View Spanning Tree Information.

Note You can disable or enable spanning tree protection on a circuit-by-circuit basis only for single-card, point-to-point Ethernet circuits. Other E-Series Ethernet configurations disable or enable spanning tree on a port-by-port basis.

Step 23In the Circuit Attributes area, confirm that the following information is correct:

Circuit name

Circuit type

Circuit size

ONS nodes

Step 24 If the information is not correct, click the Back button and repeat Steps 8 through 23 with the correct information. If the information is correct, check Route Automatically.

Note This procedure requires the use of automatic routing. Automatic routing is not available if both the Automatic Circuit Routing NE default and the Network Circuit Automatic Routing Overridable NE default are set to FALSE. For a full description of these defaults see the “Network Element Defaults” appendix in the Cisco ONS 15454 Reference Manual.

Step 1 Complete the A60 Log into CTC at the node where you will create the circuit. If you are already logged in, continue with Step 4.

Name—Assign a name to the circuit. The name can be alphanumeric and up to 48 characters (including spaces). Circuit names should be 43 characters or less if you want the ability to create monitor circuits. If you leave the field blank, CTC assigns a default name to the circuit.

State—Choose the administrative state to apply to all of the cross-connects in a circuit:

– IS—Puts the circuit cross-connects in the IS-NR service state.

– OOS,DSBLD—Puts the circuit cross-connects in the OOS-MA,DSBLD service state. Traffic is not passed on the circuit.

– IS,AINS—Puts the circuit cross-connects in the OOS-AU,AINS service state and suppresses alarms and conditions. When the connections receive a valid signal, the service state automatically changes to IS-NR.

– OOS,MT—Puts the circuit cross-connects in the OOS-MA,MT service state. The maintenance state does not interrupt traffic flow; it suppresses alarms and conditions and allows loopbacks to be performed on the circuit. Use OOS,MT for circuit testing or to suppress circuit alarms temporarily. Change the administrative state to IS; IS,AINS; or OOS,DSBLD when testing is complete. See the A230 Change a Circuit Service State.

For additional information about circuit service states, refer to the “Circuits and Tunnels” chapter in the Cisco ONS 15454 Reference Manual.

Apply to drop ports—Check this check box if you want to apply the state chosen in the State field (IS or OOS-MT only) to the Ethernet circuit source and destination ports. You cannot apply OOS-AINS to E-Series Ethernet card ports. CTC applies the circuit state to the ports only if the circuit bandwidth is the same as the port bandwidth or, if the port bandwidth is larger than the circuit, the circuit must be the first circuit to use the drop port. If not, a Warning dialog box shows the ports where the circuit state could not be applied. If the box is unchecked, CTC does not change the state of the source and destination ports. For the requirements necessary to apply a service state to drop ports, refer to the Cisco ONS 15454 Reference Manual.

Note If ports managed into the IS administrative state are not receiving signals, loss of signal alarms are generated and the port service state transitions to OOS-AU,FLT.

Step 1 Complete the A60 Log into CTC at the node where you will create the circuit. If you are already logged in, continue with Step 2.

Step 2If a high number of VLANs is already used by the network, complete the A99 Determine Available VLANs to verify that sufficient VLAN capacity is available. (You will create a VLAN during each circuit creation task.)

Name—Assign a name to the circuit. The name can be alphanumeric and up to 48 characters (including spaces). Circuit names should be 43 characters or less if you want the ability to create monitor circuits. If you leave the field blank, CTC assigns a default name to the circuit.

Step 30Confirm the circuit information that appears in the Edit Circuit dialog box and click Close.

The first and second Ethernet manual cross-connect endpoints will be bridged by the OC-N STS cross-connect circuit.

Note The appropriate STS circuit must exist in the non-ONS equipment to connect the two Ethernet manual cross-connect endpoints.

Caution If a
CARLOSS alarm repeatedly appears and clears on an Ethernet manual cross-connect,
the two Ethernet circuits might have a circuit-size mismatch. For example, a circuit size of STS-3c was configured on the first ONS 15454
and circuit size of STS-12c was configured on the second ONS 15454. Refer to the Cisco ONS 15454 Troubleshooting Guide if the alarm persists
.

This procedure assumes that you completed facility loopback tests to test the fibers and cables from the source and destination ONS 15454s to the fiber distribution page or the DSX, and one of the following procedures:

Step 7 At the destination node, connect the Ethernet test set to the destination port and configure the test set to send and receive the appropriate Ethernet traffic.

Note At this point, you are not able to send and receive Ethernet traffic.

Step 8At the source node, connect an Ethernet test set to the source port and configure the test set to send and receive the appropriate Ethernet traffic.

Step 9 Transmit Ethernet frames between both test sets. If you cannot transmit and receive Ethernet traffic between the nodes, repeat Steps 1 through 8 to make sure that you configured the Ethernet ports and test set correctly.

Note This procedure requires the use of automatic routing. Automatic routing is not available if both the Automatic Circuit Routing NE default and the Network Circuit Automatic Routing Overridable NE default are set to FALSE. For a full description of these defaults see the “Network Element Defaults” appendix in the Cisco ONS 15454 Reference Manual.

Note In this procedure, cross-connect refers to a circuit connection created within the same node between the Ethernet card and an OC-N card connected to third-party equipment. You create cross-connects at the source and destination nodes so an Ethernet circuit can be routed from source to destination across third-party equipment.

Step 1 Complete the A60 Log into CTC at the node where you will create the cross-connect. If you are already logged in, continue with Step 2.

Step 6 In the Create Circuits dialog box, complete the following fields:

Circuit Type—Choose STS.

Number of Circuits—Leave the default unchanged (1).

Auto-ranged—Unavailable.

Step 7 Click Next.

Step 8 Define the circuit attributes:

Name—Assign a name to the source cross-connect. The name can be alphanumeric and up to 48 characters (including spaces). Circuit names should be 43 characters or less if you want the ability to create monitor circuits. If you leave the field blank, CTC assigns a default name to the source cross-connect.

Size—Choose the size of the circuit that will be carried by the cross-connect. Valid sizes for a G-Series circuit are STS-1, STS-3c, STS-6c, STS-9c, STS-12c, STS-24c, and STS-48c. For an E-Series card in port-mapped mode, valid sizes are STS-1, STS-3c, STS-6c, and STS-12c.

d. In the TXP Mode column, choose RX Only from the drop-down list. CTC completes the Port B TXP Port with Port A and TXP Mode with TX Only.

NTP-A149 Test G-Series Circuits

Purpose

This procedure tests circuits created on G-Series cards.

Tools/Equipment

Ethernet test set and appropriate fibers

Prerequisite Procedures

This procedure assumes that you completed facility loopback tests to test the fibers and cables from the source and destination ONS 15454s to the fiber distribution page or the DSX, and one of the following procedures:

Step 7 At the destination node, connect the Ethernet test set to the destination port and configure the test set to send and receive the appropriate Ethernet traffic.

Note At this point, you are not able to send and receive Ethernet traffic.

Step 8At the source node, connect an Ethernet test set to the source port and configure the test set to send and receive the appropriate Ethernet traffic.

Step 9 Transmit Ethernet frames between both test sets. If you cannot transmit and receive Ethernet traffic between the nodes, repeat Steps 1 through 8 to make sure you configured the Ethernet ports and test set correctly.

Note This procedure requires the use of automatic routing. Automatic routing is not available if both the Automatic Circuit Routing NE default and the Network Circuit Automatic Routing Overridable NE default are set to FALSE. For a full description of these defaults see the “Network Element Defaults” appendix in the Cisco ONS 15454 Reference Manual.

Step 1 Complete the A60 Log into CTC at the node where you will create the VCAT circuit. If you are already logged in, continue with Step 2.

Step 2Complete the following as necessary (you can provision Ethernet or POS ports before or after the VCAT circuit is created):

Name—Assign a name to the circuit. The name can be alphanumeric and up to 48 characters (including spaces). Circuit names should be 43 characters or less if you want the ability to create monitor circuits. If you leave the field blank, CTC assigns a default name to the circuit.

Type—Displays the circuit type you chose in Step 5. You cannot change it.

Bidirectional—Checked is the default. You cannot change it.

Create cross-connects only (TL1-like)—Check this box if you want to create one or more cross-connects to complete a signal path for TL1-generated circuits.

State—Choose IS.

Apply to drop ports—Check this check box to apply the IS administrative state to the circuit source and destination ports. CTC applies the administrative state to the ports only if the circuit bandwidth is the same as the port bandwidth or, if the port bandwidth is larger than the circuit, the circuit must be the first circuit to use the port. If not, a Warning dialog box shows the ports where the administrative state could not be applied. If the check box is unchecked, CTC does not change the service state of the source and destination ports.

Note If ports managed into the IS administrative state are not receiving signals, loss of signal alarms are generated and the port service state transitions to OOS-AU,FLT.

Symmetric—Checked is the default. You cannot change it.

Open VCAT—Check this check box if you are creating open-ended VCAT circuits. For more information on open-ended VCAT, refer to the “Circuits and Tunnels” chapter in the Cisco ONS 15454 Reference Manual.

Member size—Choose the member size. For information about the member size supported for each card, refer to the “Circuits and Tunnels” chapter in the Cisco ONS 15454 Reference Manual.

Num. of members—Choose the number of members. For information about the number of members supported for each card, refer to the “Circuits and Tunnels” chapter in the Cisco ONS 15454 Reference Manual.

Note When creating open-ended VCAT circuits the number of members must be the same on each side of the virtual concatenated group (VCG). The configuration with different number of members on each side of circuit is not supported. This is applicable to circuits created on CE-Series and ML-Series cards.

Mode—Choose the protection mode for the VCAT circuit. For information about the mode supported for each card, refer to the “Circuits and Tunnels” chapter in the Cisco ONS 15454 Reference Manual.

– None—Provides no protection. A failure on one member causes the entire VCAT circuit to fail. For CE-Series cards, you can add or delete members after creating a VCAT circuit with no protection. During the time it takes to add or delete members (from seconds to minutes), the entire VCAT circuit will be unable to carry traffic. For all other cards, you cannot add or delete members if the protection mode is None.

Note While deleting SW-LCAS circuit members change the administrative state of the members to OOS,DSBLD. This is applicable to circuits created on CE-Series and ML-Series cards.

– LCAS—Sets the VCAT circuit to use LCAS. With LCAS, you can add or delete members without interrupting the operation of uninvolved members, and if a member fails, LCAS temporarily removes the failed member from the VCAT circuit. The remaining members carry the traffic until the failure clears.

Note Cisco recommends using LCAS for CE-100T-8 cards that do not need to interoperate with ML-Series cards.

Note While deleting HW-LCAS circuit members change the administrative state of the members to OOS,OOG. This is applicable to circuits created on CE-Series and ML-Series cards.

Using Required Nodes/Spans—Check this check box to specify nodes and spans to include or exclude in the CTC-generated circuit route.

Including nodes and spans for a circuit ensures that those nodes and spans are in the working path of the circuit (but not the protect path). Excluding nodes and spans ensures that the nodes and spans are not in the working or protect path of the circuit.

Review Route Before Creation—Check this check box to review and edit the circuit route before the circuit is created.

Figure 6-15 Automatically Routing a VCAT Circuit

Step 11 If the VCAT circuit has a source or destination on a CE-Series card, choose one of the following routing types.

Common Routing—Routes the members on the same fiber.

Split Routing—Allows the individual members to be routed on different fibers or each member to have different routing constraints. Split routing is required when creating circuits over a path protection configuration.

If the VCAT circuit does not have a source or destination on a CE-Series card, common routing is automatically selected and you cannot change it.

Step 12 If you want to set preferences for individual members, complete the following in the Member Preferences area. Repeat for each member. To set identical preferences for all members, skip this step and continue with Step 13:

Number—Choose a number (between 1 and 256) from the drop-down list to identify the member.

Name—Type a unique name to identify the member. The name can be alphanumeric and up to 48 characters (including spaces). If you leave the field blank, CTC assigns a default name to the circuit.

Protection—Choose the member protection type:

– Fully Protected—Routes the circuit on a protected path.

– Unprotected—Creates an unprotected circuit.

– PCA—Routes the circuit on a BLSR protection channel.

– DRI—(Split routing only) Routes the member on a dual-ring interconnect circuit.

Node-Diverse Path—(Split routing only) Available for each member when Fully Protected is chosen.

Step 13To set preferences for all members, complete the following in the Set Preferences for All Members area:

Protection—Choose the member protection type:

– Fully Protected—Routes the circuit on a protected path.

– Unprotected—Creates an unprotected circuit.

– PCA—Routes the member on a BLSR protection channel.

– DRI—(Split routing only) Routes the member on a dual-ring interconnect circuit.

Node-Diverse Path—(Split routing only) Available when Fully Protected is chosen.

Step 14 Click Next. If you chose Fully Protected or PCA, click OK to continue. If not, continue with the next step.

Step 15If you selected Using Required Nodes/Spans in Step 10, complete the following substeps. If not, continue with Step 16:

a.In the Circuit Constraints area (Figure 6-16), choose the member that you want to route from the Route member number drop-down list.

b. Click a node or span on the circuit map.

c.Click Include to include the node or span in the circuit, or click Exclude to exclude the node or span from the circuit. The order in which you choose included nodes and spans is the order in which the circuit is routed. Click spans twice to change the circuit direction.

d. Repeat Steps b and c for each node or span you wish to include or exclude.

e.Review the circuit route. To change the circuit routing order, choose a node in the Required Nodes/Lines or Excluded Nodes Links lists, then click the Up or Down buttons to change the circuit routing order. Click Remove to remove a node or span.

Step 16If you selected Review Route Before Creation in Step 10, complete the following substeps; otherwise, continue with Step 17:

a.In the Route Review/Edit area, choose the member that you want to route from the Route member number drop-down list.

b. Click a node or span on the circuit map.

c. Review the circuit route. To add or delete a circuit span, choose a node on the circuit route. Blue arrows show the circuit route. Green arrows indicate spans that you can add. Click a span arrowhead, then click Include to include the span or Remove to remove the span.

d.If the provisioned circuit does not reflect the routing and configuration you want, click Back to verify and change circuit information. If the circuit needs to be routed to a different path, see the A265 Create a Manually Routed VCAT Circuit to assign the circuit route yourself.

Name—Assign a name to the circuit. The name can be alphanumeric and up to 48 characters (including spaces). Circuit names should be 43 characters or less if you want the ability to create monitor circuits. If you leave the field blank, CTC assigns a default name to the circuit.

Type—Displays the circuit type you chose in Step 5. You cannot change it.

Bidirectional—Checked is the default. You cannot change it.

Create cross-connects only (TL1-like)—Check this box if you want to create one or more cross-connects to complete a signal path for TL1-generated circuits.

State—Choose IS.

Apply to drop ports—Check this check box to apply the IS administrative state to the circuit source and destination ports. CTC applies the administrative state to the ports only if the circuit bandwidth is the same as the port bandwidth or, if the port bandwidth is larger than the circuit, the circuit must be the first circuit to use the port. If not, a Warning dialog box shows the ports where the administrative state could not be applied. If the check box is unchecked, CTC does not change the service state of the source and destination ports.

Symmetric—Checked is the default. You cannot change it.

Open VCAT—Check this check box if you are creating open-ended VCAT circuits. For more information on open-ended VCAT refer to the “Circuits and Tunnels” chapter in the Cisco ONS 15454 Reference Manual.

Member size—Choose the member size. For information about the member size supported for each card, refer to the “Circuits and Tunnels” chapter in the Cisco ONS 15454 Reference Manual.

Num. of members—Choose the number of members. For information about the number of members supported for each card, refer to the “Circuits and Tunnels” chapter in the Cisco ONS 15454 Reference Manual. You can add additional members using the Edit circuit function.

Note When creating open-ended VCAT circuits the number of members must be the same on each side of the virtual concatenated group (VCG). The configuration with different number of members on each side of circuit is not supported. This is applicable to circuits created on CE-Series and ML-Series cards.

Mode—Choose the protection mode for the VCAT circuit. For information about the mode supported for each card, refer to the “Circuits and Tunnels” chapter in the Cisco ONS 15454 Reference Manual.

– None—Provides no protection. A failure on one member causes the entire VCAT circuit to fail. For CE-Series cards, you can add or delete members after creating a VCAT circuit with no protection. During the time it takes to add or delete members (from seconds to minutes), the entire VCAT circuit will be unable to carry traffic. For all other cards, you cannot add or delete members if the protection mode is None.

– SW-LCAS—Allows the VCAT circuit to adapt to member failures and keep traffic flowing after failures at a reduced bandwidth. Sw-LCAS uses legacy SONET failure indicators like AIS-P and RDI-P to detect member failure.

Note While deleting SW-LCAS circuit members change the administrative state of the members to OOS,DSBLD. This is applicable to circuits created on CE-Series and ML-Series cards.

– LCAS—Sets the VCAT circuit to use LCAS. With LCAS, you can add or delete members without interrupting the operation of uninvolved members, and if a member fails, LCAS temporarily removes the failed member from the VCAT circuit. The remaining members carry the traffic until the failure clears.

Note Cisco recommends using LCAS for CE-T100-8 cards that do not need to interoperate with the ML-Series cards.

Note While deleting HW-LCAS circuit members change the administrative state of the members to OOS,OOG. This is applicable to circuits created on CE-Series and ML-Series cards.

Step 11 If the VCAT circuit has a source or destination on a CE-Series card, choose one of the following routing types.

Common Routing—Routes the members on the same fiber.

Split Routing—Allows the individual members to be routed on different fibers or each member to have different routing constraints. Split routing is required when creating circuits over a path protection configuration.

If the VCAT circuit does not have a source or destination on a CE-Series card, common routing is automatically selected and you cannot change it.

Step 12 If you want to set preferences for individual members, complete the following in the Member Preferences area. Repeat for each member. To set identical preferences for all members, skip this step and continue with Step 13.

Number—Choose a number (between 1 and 256) from the drop-down list to identify the member.

Name—Type a unique name to identify the member. The name can be alphanumeric and up to 48 characters (including spaces). If you leave the field blank, CTC assigns a default name to the circuit.

Protection—Choose the member protection type:

– Fully Protected—Routes the circuit on a protected path.

– Unprotected—Creates an unprotected circuit.

– PCA—Routes the member on a BLSR protection channel.

– DRI—(Split routing only) Routes the member on a dual-ring interconnect circuit.

Node-Diverse Path—(Split routing only) Available for each member when Fully Protected is chosen.

Step 13To set preferences for all members, complete the following in the Set Preferences for All Members area:

Protection—Choose the member protection type:

– Fully Protected—Routes the circuit on a protected path.

– Unprotected—Creates an unprotected circuit.

– PCA—Routes the member on a BLSR protection channel.

– DRI—(Split routing only) Routes the member on a dual-ring interconnect circuit.

Node-Diverse Path—(Split routing only) Available when Fully Protected is chosen.

Step 14 Click Next. If you chose Fully Protected or PCA, click OK to continue. If not, continue with the next step.

Step 15 In the Route Review and Edit area, node icons appear so you can route the circuit manually.

Note The SDCCs and LDCCs should not be provisioned between SONET (ANSI) and SDH (ETSI) nodes using CTC or TL1 because they cannot operate between SONET and SDH nodes. These communication channels should be provisioned on similar nodes, such as SONET-to-SONET or SDH-to-SDH. To establish communication channels between SONET and SDH nodes, create a DCC tunnel. See the A313 Create a DCC Tunnel to create a DCC tunnel.

Step 1 Complete the A60 Log into CTC at the node where you will create the overhead circuit. If you are already logged in, continue with Step 2.

Number of Circuits—Enter the number of circuits that you want to create. The default is 1.

Auto-ranged—(Automatically routed circuits only) If you entered more than 1 in the Number of Circuits field, uncheck this box. (The box is unavailable if only one circuit is entered in the Number of Circuits field.)

Step 6 Click Next.

Step 7Define circuit attributes:

Name—Assign a name to the circuit. The name can be alphanumeric and up to 48 characters (including spaces). Circuit names should be 43 characters or less if you want the ability to create monitor circuits. If you leave the field blank, CTC assigns a default name to the circuit.

Create cross-connects only (TL1-like)—Check this box if you want to create one or more cross-connects to complete a signal path for TL1-generated circuits. If you check this box, VT tunnels and Ethergroup sources and destinations are unavailable.

State—Choose the administrative state to apply to all of the cross-connects in a circuit:

– IS—Puts the circuit cross-connects in the IS-NR service state.

– OOS,DSBLD—Puts the circuit cross-connects in the OOS-MA,DSBLD service state. Traffic is not passed on the circuit.

– IS,AINS—Puts the circuit cross-connects in the OOS-AU,AINS service state and suppresses alarms and conditions. When the connections receive a valid signal, the service state automatically changes to IS-NR.

– OOS,MT—Puts the circuit cross-connects in the OOS-MA,MT service state. The maintenance state does not interrupt traffic flow; it suppresses alarms and conditions and allows loopbacks to be performed on the circuit. Use OOS,MT for circuit testing or to suppress circuit alarms temporarily. Change the administrative state to IS; IS,AINS; or OOS,DSBLD when testing is complete. See the A230 Change a Circuit Service State.

For additional information about circuit service states, refer to the “Circuits and Tunnels” chapter in the Cisco ONS 15454 Reference Manual.

Apply to drop ports—Check this check box if you want to apply the administrative state chosen in the State field to the circuit source and destination ports. CTC applies the administrative state to the ports only if the circuit bandwidth is the same as the port bandwidth or, if the port bandwidth is larger than the circuit, the circuit must be the first circuit to use the port. If not, a Warning dialog box displays the ports where the administrative state could not be applied. If the check box is unchecked, CTC does not apply the administrative state to the source and destination ports.

Note If ports managed into the IS administrative state are not receiving signals, loss of signal alarms are generated and the port service state transitions to OOS-AU,FLT.

Protected Drops—Check this check box if you want the circuit routed to protect drops only, that is, to ONS 15454 cards that are in 1:1, 1:N, 1+1, or optimized 1+1 protection. If you check this check box, CTC provides only protected cards as source and destination choices.

Step 8 Click Next.

Step 9Choose the circuit source:

a.From the Node drop-down list, choose the node where the circuit will originate.

b.From the Slot drop-down list, choose the slot containing the card where the circuit originates. (If card capacity is fully utilized, it does not appear in the list.)

c.Depending on the circuit origination card, choose the source port and/or STS from the Port and STS drop-down lists. The Port drop-down list is only available if the card has multiple ports. STSs do not appear if they are already in use by other circuits.

Note The STSs that appear depend on the card, circuit size, and protection scheme.

Step 10 Click Next.

Step 11 Choose the circuit destination:

Note The destination port must be located on the same node as the circuit source port.

b. From the Slot drop-down list, choose the slot containing the card where the circuit will terminate (destination card). (If a card’s capacity is fully utilized, the card does not appear in the list.)

c.Depending on the card selected in Step b, choose the destination port and/or STS from the Port and STS drop-down lists. The Port drop-down list is available only if the card has multiple ports. The STSs that appear depend on the card, circuit size, and protection scheme.

To route the test circuit on a BLSR protection channel, check Protection Channel Access, click Yes in the Warning dialog box, then continue with Step 15.

Caution Circuits routed on BLSR protection channels are not protected and are preempted during BLSR switches.

Step 15Click Next.

Step 16In the Route Review/Edit area, node icons appear for you to route the circuit manually:

a. In the Route Review/Edit area, click the source node icon if it is not already selected.

b.Starting with a span on the source node, click the arrow of the span you want the circuit to travel. To reverse the direction of the arrow, click the arrow twice.

c. The arrow turns white. In the Selected Span area, the From and To fields provide span information. The source STS appears. If you want to change the source STS, adjust the Source STS field; otherwise, continue with Step d.

d.Click Add Span. The span is added to the Included Spans list and the span arrow turns blue.

e. Repeat Steps b through d until the circuit is provisioned from the source to the destination node through all intermediary nodes.

Step 17 Click Finish. If the path does not meet the specified path diversity requirement, CTC displays an error message and allows you to change the circuit path. If you entered more than 1 in the Number of Circuits field on the Circuit Creation dialog box, the Circuit Creation dialog box appears after the circuit is created so you can create the remaining circuits. Repeat Steps 7 through 16 for each additional circuit.

Step 18 When all the circuits are created, the main Circuits window appears. Verify that the circuits you created appear in the window.

Stop. You have completed this procedure.

NTP-A326 Create a Server Trail

Purpose

This procedure creates a server trail, which provides a connection between ONS nodes through a third-party network. You can create server trails between any two optical ports.

Protection Type—Choose one of the following protection types: Preemptible, Unprotected, or Fully Protected. The server trail protection sets the protection type for any circuit that traverses it.

– Preemptible— PCA circuits will use server trails with the Preemptible attribute.

– Unprotected—In Unprotected Server Trail, CTC assumes that the circuits going out from that specific port will not be protected by provider network and will look for a secondary path from source to destination if you are creating a protected circuit.

– Fully Protected—In Fully Protected Server Trail, CTC assumes that the circuits going out from that specific port will be protected by provider network and will not look for a secondary path from source to destination.

Number of Trails—Enter the number of server trails. Number of trails determine the number of circuits that can be created on server trail. You can create a maximum of 3744 server trails on a node. You can create multiple server trails from the same port. This is determined by how many circuits of a particular server trail size can be supported on the port (for example, you can create 12 STS-1 server trails from one OC-12 port or two STS3c and six STS-1 server trails from same port).

SRLG—Enter a value for the Shared Resource Link Group (SRLG). SRLG is used by Cisco Transport Manager (CTM) to specify link diversity. The SRLG field has no restrictions. If you create multiple server trails from one port, you can assign the same SRLG value to all the links to indicate that they originate from the same port.

Step 6 Click Next.

Step 7 In the Source area, complete the following:

From the Node drop-down list, choose the node where the server trail will originate.

From the Slot drop-down list, choose the slot containing the card where the server trail originates. (If a card’s capacity is fully utilized, the card does not appear in the list.)

Depending on the origination card, choose the source port and/or STS or VT from the Port and STS or VT lists. The Port list is only available if the card has multiple ports. STSs and VTs do not appear if they are already in use by other circuits.

Step 8 Click Next.

Step 9 In the Destination area, complete the following:

From the Node drop-down list, choose the destination node.

From the Slot drop-down list, choose the slot containing the card where the server trail will terminate (destination card). (If a card’s capacity is fully utilized, the card does not appear in the list.)

Depending on the card selected, choose the destination port and/or STS or VT from the Port and STS or VT drop-down lists. The Port drop-down list is available only if the card has multiple ports. The STSs that appear depend on the card, circuit size, and protection scheme.

Step 10 Click Finish.

Note When Server Trails are created on an IPv4 or IPv6 node and the IP address of the node changes, complete the A599 Repair Server Trails to repair the Server Trails.

Note This procedure requires the use of automatic routing. Automatic routing is not available if both the Automatic Circuit Routing NE default and the Network Circuit Automatic Routing Overridable NE default are set to FALSE. For a full description of these defaults see the “Network Element Defaults” appendix in the Cisco ONS 15454 Reference Manual.

Note This procedure is necessary when you need to route VT traffic between a path protection configuration across an ONS 15600 hub node to a line-protected domain. For more information about the ONS 15600 as a hub node for mixed ONS 15454 protection domains, refer to the “Turn Up Network” chapter in the Cisco ONS 15600 Procedure Guide and the “Circuits and Tunnels” chapter in the Cisco ONS 15600 Reference Manual.

Step 1 Complete the A60 Log into CTC at the node where you will create the circuit. If you are already logged in, continue with Step 2.

Step 2 If you want to assign a name to the circuit source and destination ports before you create the circuit, complete the A314 Assign a Name to a Port. If not, continue with Step 3.

Circuit Type—Choose VT or STS. If you are creating an open-ended path protection circuit to route VT traffic across an ONS 15600 hub node with mixed protection domains, choose VT.

Number of Circuits—Enter the number of circuits that you want to create. The default is 1. If you are creating multiple circuits with the same slot and sequential port numbers, you can use Auto-ranged to create the circuits automatically.

Auto-ranged—This check box is automatically selected if you enter more than 1 in the Number of Circuits field. Auto-ranging creates identical (same source and destination) sequential circuits automatically. Uncheck the box if you do not want CTC to create sequential circuits automatically.

Name—Assign a name to the circuit. The name can be alphanumeric and up to 48 characters, (including spaces). Circuit names should be 43 characters or less if you want the ability to create monitor circuits. If you leave the field blank, CTC assigns a default name to the circuit.

Size—If the circuit type is VT, choose VT1.5. If the circuit type is STS, choose STS-1.

Bidirectional—Leave checked for this circuit (default).

Create cross-connects only (TL1-like)—Check this check box to create one or more cross-connects to complete a signal path for TL1-generated circuits. If you are creating an open-ended path protection circuit to bridge VT traffic, you must check this check box.

Diagnostic—Leave unchecked.

State—Choose the administrative state to apply to all of the cross-connects in a circuit:

– IS—Puts the circuit cross-connects in the In-Service and Normal (IS-NR) service state.

– OOS,DSBLD—Puts the circuit cross-connects in the Out-of-Service and Management, Disabled (OOS-MA,DSBLD) service state. Traffic is not passed on the circuit.

– IS,AINS—Puts the circuit cross-connects in the Out-of-Service and Autonomous, Automatic In-Service (OOS-AU,AINS) service state and suppresses alarms and conditions. When the connections receive a valid signal, the service state automatically changes to IS-NR.

– OOS,MT—Puts the circuit cross-connects in the Out-of-Service and Management, Maintenance (OOS-MA,MT) service state. The maintenance state does not interrupt traffic flow; it suppresses alarms and conditions and allows loopbacks to be performed on the circuit. Use OOS,MT for circuit testing or to suppress circuit alarms temporarily. Change the administrative state to IS; IS,AINS; or OOS,DSBLD when testing is complete. See the A230 Change a Circuit Service State.

For additional information about circuit service states, refer to the “Circuits and Tunnels” chapter in the Cisco ONS 15454 Reference Manual.

Apply to drop ports—Check this check box if you want to apply the administrative state chosen in the State field to the circuit source and destination ports. CTC applies the administrative state to the ports only if the circuit bandwidth is the same as the port bandwidth or, if the port bandwidth is larger than the circuit, the circuit must be the first circuit to use the port. If not, a Warning dialog box displays the ports where the administrative state could not be applied. If the check box is unchecked, CTC does not apply the administrative state to the source and destination ports.

Note If ports managed into the IS administrative state are not receiving signals, loss of signal alarms are generated and the port service state transitions to OOS-AU,FLT.

Protected Drops—Check this box if you want the circuit routed on protected drops only, that is, to ONS 15454 cards that are in 1:1, 1:N, 1+1, or optimized 1+1 protection. If you check this box, CTC displays only protected cards and ports as source and destination choices.

Using Required Nodes/Spans—Check this check box if you want to specify nodes and spans to include or exclude in the CTC-generated circuit route.

Including nodes and spans for a circuit ensures that those nodes and spans are in the working path of the circuit (but not the protect path). Excluding nodes and spans ensures that the nodes and spans are not in the working or protect path of the circuit.

Review Route Before Creation—Check this check box if you want to review and edit the circuit route before the circuit is created.

Step 12 Leave Fully Protected Path checked.

Step 13 Choose one of the following:

Nodal Diversity Required—Ensures that the primary and alternate paths within path protection portions of the complete circuit path are nodally diverse.

Nodal Diversity Desired—Specifies that node diversity is preferred, but if node diversity is not possible, CTC creates fiber-diverse paths for the path protection portion of the complete circuit path.

Link Diversity Only—Specifies that only fiber-diverse primary and alternate paths for path protection portions of the complete circuit path are needed. The paths might be node-diverse, but CTC does not check for node diversity.

Step 14 If you selected Using Required Nodes/Spans in Step 11, complete the following substeps. If not, continue with Step 15.

a. Click Next.

b.In the Circuit Route Constraints area, click a node or span on the circuit map.

c. Click Include to include the node or span in the circuit. Click Exclude to exclude the node or span from the circuit. The order in which you choose included nodes and spans is the order in which the circuit is routed. Click spans twice to change the circuit direction.

d. Repeat Steps b and c for each node or span you wish to include or exclude.

e. Review the circuit route. To change the circuit routing order, choose a node in the Required Nodes/Lines or Excluded Nodes Links lists and click the Up or Down buttons to change the circuit routing order. Click Remove to remove a node or span.

Step 15Click Next. If the circuit you are creating is a VT circuit for routing traffic over an ONS 15600 hub node, in the Create area of the VT Matrix Optimization page choose Create VT tunnel on transit nodes and click Next. If not, continue with Step 16.

This option is available if the circuit passes through a node that does not have a VT tunnel, or if an existing VT tunnel is full. VT tunnels allow VT circuits to pass through ONS 15454s without consuming cross-connect card resources. VT tunnels can carry 28 VT1.5 circuits. In general, creating VT tunnels is a good idea if you are creating many VT circuits from the same source and destination. Refer to the Cisco Cisco ONS 15454 Reference Manual for more information.

Step 16If you selected Review Route Before Creation in Step 11, complete the following substeps. If not, continue with Step 17.

a. Click Next.

b.Review the circuit route. To add or delete a circuit span, choose a node on the circuit route. Blue arrows show the circuit route. Green arrows indicate spans that you can add. Click a span arrowhead, then click Include to include the span or Remove to remove the span.

c. If the provisioned circuit does not reflect the routing and configuration you want, click Back to verify and change circuit information.

Step 17Click Finish. One of the following results occurs if you entered more than one circuit in the Number of Circuits field on the Circuit Creation dialog box.

If you chose Auto-ranged, CTC automatically creates the number of circuits entered in the Number of Circuits field. If auto-ranging cannot complete all the circuits, for example, because sequential ports are unavailable at the source or destination, a dialog box appears. Set the new source or destination for the remaining circuits, then click Finish to continue auto-ranging. After completing the circuits, the Circuits window appears.

If you did not choose Auto-ranged, the Circuit Creation dialog box appears so you can create the remaining circuits. Repeat Steps 5 through 17 for each additional circuit. After completing the circuits, the Circuits window appears.

Step 18 In the Circuits window, verify that the new circuits appear in the circuits list.

Step 19 Complete one of the following to test the circuit. Skip this step if you built a test circuit.

Step 1 Complete the A60 Log into CTC at the node where you will create the circuit. If you are already logged in, continue with Step 2.

Step 2If you want to assign a name to the source and destination ports before you create the circuit, complete the A314 Assign a Name to a Port. If not, continue with Step 3.

Step 3From the View menu, choose Go to Network View.

Step 4 Click the Circuits tab, then click Create.

Step 5 In the Circuit Creation dialog box, complete the following fields:

Circuit Type—Choose STS.

Number of Circuits—Enter the number of circuits that you want to create. The default is 1.

Auto-ranged—Uncheck this checkbox.

Note If specify the number of circuits as more than 1 and if the auto-ranged check box is selected, the Route Automatically check box in the Circuit Routing Preferences area is automatically checked; this prevents you from creating an overlay ring circuit.

Step 6 Click Next.

Step 7Define circuit attributes:

Name—Assign a name to the circuit. The name can be alphanumeric and up to 48 characters (including spaces). Circuit names should be 43 characters or less if you want the ability to create monitor circuits. If you leave the field blank, CTC assigns a default name to the circuit.

Create cross-connects only (TL1-like)—Check this box if you want to create one or more cross-connects to complete a signal path for TL1-generated circuits. If you check this box, VT tunnels and Ethergroup sources and destinations are unavailable.

State—Choose the administrative state to apply to all of the cross-connects in a circuit:

– IS—Puts the circuit cross-connects in the IS-NR service state.

– OOS,DSBLD—Puts the circuit cross-connects in the OOS-MA,DSBLD service state. Traffic is not passed on the circuit.

– IS,AINS—Puts the circuit cross-connects in the OOS-AU,AINS service state and suppresses alarms and conditions. When the connections receive a valid signal, the service state automatically changes to IS-NR.

– OOS,MT—Puts the circuit cross-connects in the OOS-MA,MT service state. The maintenance state does not interrupt traffic flow; it suppresses alarms and conditions and allows loopbacks to be performed on the circuit. Use OOS,MT for circuit testing or to suppress circuit alarms temporarily. Change the administrative state to IS; IS,AINS; or OOS,DSBLD when testing is complete. See the A230 Change a Circuit Service State.

For additional information about circuit service states, refer to the “Circuits and Tunnels” chapter in the Cisco ONS 15454 Reference Manual.

Apply to drop ports—Check this check box if you want to apply the administrative state chosen in the State field to the circuit source and destination ports. CTC applies the administrative state to the ports only if the circuit bandwidth is the same as the port bandwidth or, if the port bandwidth is larger than the circuit, the circuit must be the first circuit to use the port. If not, a Warning dialog box displays the ports where the administrative state could not be applied. If the check box is unchecked, CTC does not apply the administrative state to the source and destination ports.

Note If ports managed into the IS administrative state are not receiving signals, Loss of Signal (LOS) alarms are generated and the port service state transitions to OOS-AU,FLT.

Protected Drops—Check this check box if you want the circuit routed to protect drops only, that is, to ONS 15454 cards that are in 1:1, 1:N, 1+1, or optimized 1+1 protection. If you check this check box, CTC provides only protected cards as source and destination choices.

Step 8 Click Next.

Step 9Choose the circuit source:

a.From the Node drop-down list, choose the node where the circuit will originate.

b. From the Slot drop-down list, choose the slot containing the card where the circuit originates. (If card capacity is fully utilized, it does not appear in the list.)

c. Depending on the circuit origination card, choose the source port and/or STS from the Port and STS drop-down lists. The Port drop-down list is only available if the card has multiple ports. STSs do not appear if they are already in use by other circuits.

Note The STSs that appear depend on the card, circuit size, and protection scheme.

Step 17 In the Route Review/Edit area, node icons appear for you to route the circuit manually:

a. In the Route Review/Edit area, click the source node icon if it is not already selected.

b.Starting with a span on the source node, click the arrow of the span you want the circuit to travel. To reverse the direction of the arrow, click the arrow twice.

c. In the Selected Span area, the From and To fields provide span information. The source STS appears. If you want to change the source STS, adjust the Source STS field; otherwise, continue with Step d.

d.Click Add Span. The span is added to the Included Spans list and the span arrow turns blue.

e. Repeat Steps b through d until the circuit is provisioned from the source to the destination node through all intermediary nodes.

Note During manual routing, while creating an overlay ring circuit, you can create loops. Creating loops allows you to return to the same node more than once while selecting the spans.

Step 18 Click Finish.

Step 19 When all the circuits are created, the main Circuits window appears. Verify that the circuits you created appear in the window.

Number of Circuits—Enter the number of circuits that you want to create. The default is 1. Leave the default unchanged (1).

Auto-ranged—Unavailable when the Number of Circuits field is 1.

Step 7 Click Next.

Step 8 Define the circuit attributes:

Name—Assign a name to the circuit. The name can be alphanumeric and up to 48 characters (including spaces). Circuit names should be 43 characters or less if you want the ability to create monitor circuits. If you leave the field blank, CTC assigns a default name to the circuit.

Size—Choose STS-1.

Bidirectional—Uncheck to create a unidirectional circuit.

Create cross-connects only (TL1-like)—Check this check box if you want to create one or more cross-connects to complete a signal path for TL1-generated circuits. If you check this box, VT tunnels and Ethergroup sources and destinations are unavailable.

State—Choose the administrative state to apply to all cross-connects in the circuit:

– IS—Puts the circuit cross-connects in the IS-NR service state.

– OOS,DSBLD—Puts the circuit cross-connects in the OOS-MA,DSBLD service state. Traffic is not passed on the circuit.

– IS,AINS—Puts the circuit cross-connects in the OOS-AU,AINS service state and suppresses alarms and conditions. When the connections receive a valid signal, the service state automatically changes to IS-NR.

– OOS,MT—Puts the circuit cross-connects in the OOS-MA,MT service state. The maintenance state does not interrupt traffic flow; it suppresses alarms and conditions and allows loopbacks to be performed on the circuit. Use OOS,MT for circuit testing or to suppress circuit alarms temporarily. Change the administrative state to IS; IS,AINS; or OOS,DSBLD when testing is complete. See the A230 Change a Circuit Service State.

For additional information about circuit service states, refer to the “Circuits and Tunnels” chapter in the Cisco ONS 15454 Reference Manual.

Apply to drop ports—Check this check box if you want to apply the administrative state chosen in the State field to the circuit source and destination ports. CTC applies the administrative state to the ports only if the circuit bandwidth is the same as the port bandwidth. If the port bandwidth is larger than the circuit, the circuit must be the first circuit to use the port. If not, a Warning dialog box displays the ports where the administrative state could not be applied. If the check box is unchecked, CTC does not apply the administrative state to the source and destination ports.

Note If ports in IS administrative state are not receiving signals, LOS (loss of signal) alarms are generated and the service state of ports change to OOS-AU,FLT.

Protected Drops—Check this check box if you want the circuit routed to protect drops only, that is, to ONS 15454 cards that are in 1:1, 1:N, 1+1, or optimized 1+1 protection. If you check this check box, CTC provides only protected cards as source and destination choices.

Step 11To set the circuit path protection, complete one of the following:

To route the circuit on a protected path, leave Fully Protected Path checked and continue with Step 12. Fully protected paths might or might not have path protection path segments (with primary and alternate paths), and the path diversity options apply only to path protection path segments, if any exist.

Caution Circuits routed on BLSR protection channels are not protected and are preempted during BLSR switches.

Step 12If you selected Fully Protected Path in Step 11 and the circuit will be routed on a path protection configuration, choose one of the following:

Nodal Diversity Required—Ensures that the primary and alternate paths within the path protection portions of the complete circuit path are nodally diverse.

Nodal Diversity Desired—Specifies that node diversity is preferred, but if node diversity is not possible, CTC creates fiber-diverse paths for the path protection portion of the complete circuit path.

Link Diversity Only—Specifies that only fiber-diverse primary and alternate paths for path protection portions of the complete circuit path are needed. The paths might be node-diverse, but CTC does not check for node diversity.

Step 13If you selected Fully Protected Path in Step 11 and the circuit will be routed on a BLSR DRI or path protection DRI, check the Dual Ring Interconnect check box.

Step 14Click Next. In the Route Review/Edit area, node icons appear for you to route the circuit manually. If you checked Dual Ring Interconnect for BLSR, continue with Step 15. If not, continue with Step 16.

Step 17In the Circuits window, click the circuit that you want to route to multiple drops. The Delete, Edit, and Search radio buttons become active.

Step 18 Click Edit. The Edit Circuit window appears with the General tab selected. All nodes in the DCC network appear on the network map. Circuit source and destination information appears under the source and destination nodes. To see a detailed view of the circuit, click Show Detailed Map. You can rearrange the node icons by selecting the node with the left mouse button while simultaneously pressing Ctrl, then dragging the icon to the new location.

c. Port, STS—Choose the port and/or STS from the Port and STS drop-down lists. The card selected in Step b determines whether port, STS, or both appear. See Table 6-2 for a list of options.

d. The routing preferences for the new drop match those of the original circuit. However, if the following options are available, you can modify them:

If the original circuit was routed on a path protected path, you can change the nodal diversity options: Nodal Diversity Required, Nodal Diversity Desired, or Link Diversity Only. See Step 12 for option descriptions.

If the original circuit was not routed on a protected path, the Protection Channel Access option is available. See Step 11 for a description of the Protection Channel Access option.

e. If you want to change the circuit state, choose the circuit state from the Target Circuit Admin State drop-down list. The state chosen applies to the entire circuit.

f. Check Apply to drop ports if you want to apply the state chosen in the Target Circuit Admin State to the circuit source and destination drops. For the requirements necessary to apply a service state to drop ports, refer to the Cisco ONS 15454 Reference Manual.

g.Click Finish. The new drop appears in the Drops list.

Step 22If you need to create additional drops for the circuit, repeat Steps 21 a through g to create the additional drops.

Step 23Click Close. The Circuits window appears.

Step 24 Verify that the new drops appear in the Destination column for the circuit you edited. If they do not appear, repeat Steps 21 a through g, making sure that all options are provisioned correctly.

Stop. You have completed this procedure.

NTP-A363 Create a Dual Source, Single Destination Circuit

Purpose

This procedure creates a dual source and single destination circuit on an ML-MR-10 card with the card port protection (CPP) enabled.

Tools/Equipment

Two ML-MR-10 cards must be installed at one end of the circuit and a CE-MR-6, CE-MR-10, or ML-MR-10 card at the other end.

Number of Circuits—Enter the number of circuits that you want to create. The default is 1.

Auto-ranged—This check box is automatically selected when you enter more than 1 in the Number of Circuits field. Leave this check box selected if you are creating multiple optical circuits with the same source and destination and you want CTC to create the circuits automatically. Uncheck the box if you do not want CTC to create the circuits automatically.

Step 7 Click Next.

Step 8 Define the circuit attributes:

Name—Assign a name to the circuit. The name can be alphanumeric and up to 48 characters (including spaces). Circuit names should be 43 characters or less if you want the ability to create monitor circuits. If you leave the field blank, CTC assigns a default name to the circuit.

Size—If the circuit type is VT, choose VT1.5. If the circuit type is STS, choose STS-1.

Create cross-connects only (TL1-like)—Check this box if you want to create one or more cross-connects to complete a signal path for TL1-generated circuits. If you check this box, VT tunnels and Ethergroup sources and destinations are unavailable.

Diagnostic—Leave unchecked.

State—Choose the administrative state to apply to all of the cross-connects in a circuit:

– IS —Puts the circuit cross-connects in the IS-NR service state.

– OOS,DSBLD —Puts the circuit cross-connects in the OOS-MA,DSBLD service state. Traffic is not passed on the circuit.

– IS,AINS —Puts the circuit cross-connects in the OOS-AU,AINS service state and suppresses alarms and conditions. When the connections receive a valid signal, the service state automatically changes to IS-NR.

– OOS,MT —Puts the circuit cross-connects in the OOS-MA,MT service state. The maintenance state does not interrupt traffic flow; it suppresses alarms and conditions and allows loopbacks to be performed on the circuit. Use OOS,MT for circuit testing or to suppress circuit alarms temporarily.

– OOS,OOG—(VCAT circuits only) Puts the member in the Out-of-Service and Management, Out-of-Group (OOS-MA,OOG) service state. This administrative state is used to place a member circuit out of the group and to stop sending traffic. OOS-MA,OOG only applies to the cross-connects on an end node where VCAT resides. The cross-connects on intermediate nodes are in the OOS-MA,MT service state. Change the administrative state to IS; IS,AINS; or OOS,DSBLD when testing is complete. See the A230 Change a Circuit Service State.

For additional information about circuit service states, refer to the “Administrative and Service States” appendix in the Cisco ONS 15454 Reference Manual.

Apply to drop ports—Check this check box if you want to apply the administrative state chosen in the State field to the circuit source and destination ports. CTC applies the administrative state to the ports only if the circuit bandwidth is the same as the port bandwidth or, if the port bandwidth is larger than the circuit, the circuit must be the first circuit to use the port. If not, a Warning dialog box displays the ports where the administrative state could not be applied. If the check box is unchecked, CTC does not apply the administrative state to the source and destination ports.

Note If ports managed into the IS administrative state are not receiving signals, loss of signal alarms are generated and the port service state transitions to OOS-AU,FLT.

Note When Route Automatically is not selected, the Using Required Nodes/Spans and Review Route Before Circuit Creation check boxes are unavailable.

Step 12To set the circuit path protection, complete one of the following:

To route the circuit on a protected path, leave Fully Protected Path checked and continue with Step 13. Fully protected paths might or might not have path protection path segments (with primary and alternate paths), and the path diversity options apply only to path protection path segments, if any exist.

Caution Circuits routed on BLSR protection channels are not protected and are preempted during BLSR switches.

Step 13If you selected Fully Protected Path in Step 12 and the circuit will be routed on a path protection configuration, choose one of the following:

Nodal Diversity Required —Ensures that the primary and alternate paths within the path protection portions of the complete circuit path are nodally diverse.

Nodal Diversity Desired —Specifies that node diversity is preferred, but if node diversity is not possible, CTC creates fiber-diverse paths for the path protection portion of the complete circuit path.

Link Diversity Only —Specifies that only fiber-diverse primary and alternate paths for path protection portions of the complete circuit path are needed. The paths might be node-diverse, but CTC does not check for node diversity.

Step 14 If you selected Fully Protected Path in Step 12 and the circuit will be routed on a BLSR DRI or path protection DRI, click the Dual Ring Interconnect check box.

Step 15Click Next. In the Route Review/Edit area, node icons appear for you to route the circuit manually.

Step 16Click Finish.

Step 17 When all the circuits are created, the main Circuits window appears. Verify that the circuits you created appear in the window.

Stop. You have completed this procedure.

NTP-A371 Manually Create a CCAT or VCAT Circuit on the CE-MR-10 Card

Purpose

This procedure manually creates a CCAT or VCAT circuit on the CE-MR-10 Card.

Name—Assign a name to the circuit. The name can be alphanumeric and up to 48 characters (including spaces). Circuit names should be 43 characters or less if you want the ability to create monitor circuits. If you leave the field blank, CTC assigns a default name to the circuit.

Type—Displays the circuit type that you chose in Step 5. You cannot change it.

Bidirectional—Checked is the default. You cannot change it.

Create cross-connects only (TL1-like)—Check this box if you want to create one or more cross-connects to complete a signal path for TL1-generated circuits.

State—Choose IS.

Apply to drop ports—Check this check box to apply the IS administrative state to the circuit source and destination ports. CTC applies the administrative state to the ports only if the circuit bandwidth is the same as the port bandwidth or, if the port bandwidth is larger than the circuit, the circuit must be the first circuit to use the port. If not, a Warning dialog box shows the ports where the administrative state could not be applied. If the check box is unchecked, CTC does not change the service state of the source and destination ports.

Symmetric—Checked is the default. You cannot change it.

Open VCAT—Check this check box if you are creating open-ended CCAT/VCAT circuits. For more information on open-ended CCAT/VCAT refer to the “Circuits and Tunnels” chapter in the Cisco ONS 15454 Reference Manual.

Member size—Choose the member size. For information about the member size supported for each card, refer to the “Circuits and Tunnels” chapter in the Cisco ONS 15454 Reference Manual.

Num. of members—Choose the number of members. For information about the number of members supported for each card, refer to the “Circuits and Tunnels” chapter in the Cisco ONS 15454 Reference Manual. You can add additional members using the Edit circuit function.

Mode—Choose the protection mode for the CCAT/VCAT circuit. For information about the mode supported for each card, refer to the “Circuits and Tunnels” chapter in the Cisco ONS 15454 Reference Manual.

– None—Provides no protection. A failure on one member causes the entire CCAT/ VCAT circuit to fail. For CE-MR-10 cards, you can add or delete members after creating a VCAT circuit with no protection. During the time it takes to add or delete members (from seconds to minutes), the entire VCAT circuit will be unable to carry traffic. For all other cards, you cannot add or delete members if the protection mode is None.

– SW-LCAS—Allows the VCAT circuit to adapt to member failures and keep traffic flowing after failures at a reduced bandwidth. Sw-LCAS uses legacy SONET failure indicators like AIS-P and RDI-P to detect member failure.

– LCAS—Sets the VCAT circuit to use LCAS. With LCAS, you can add or delete members without interrupting the operation of uninvolved members, and if a member fails, LCAS temporarily removes the failed member from the VCAT circuit. The remaining members carry the traffic until the failure clears.

Note For CE-MR-10 card, before you create a VCAT circuit with LCAS protection mode, it is recommended that you put all members of the VCAT circuit being created in OOS-OOG service state and later move them to IS state.

Step 11 If the VCAT circuit has a source or destination on a CE-MR-10 card, choose one of the following routing types.

Common Fiber Routing—Routes the members on the same fiber.

Split Routing—Allows the individual members to be routed on different fibers or each member to have different routing constraints. Split routing is required when creating circuits over a path protection configuration.

If the VCAT circuit does not have a source or destination on a CE-MR-10 card, common routing is automatically selected and you cannot change it.

Step 12 If you want to set preferences for individual members, complete the following in the Member Preferences area. Repeat for each member. To set identical preferences for all members, skip this step and continue with Step 13.

Number—Choose a number (between 1 and 256) from the drop-down list to identify the member.

Name—Type a unique name to identify the member. The name can be alphanumeric and up to 48 characters (including spaces). If you leave the field blank, CTC assigns a default name to the circuit.

Protection—Choose the member protection type:

– Fully Protected—Routes the circuit on a protected path.

– Unprotected—Creates an unprotected circuit.

– PCA—Routes the member on a BLSR protection channel.

– DRI—(Split routing only) Routes the member on a dual-ring interconnect circuit.

Node-Diverse Path—(Split routing only) Available for each member when Fully Protected is chosen.

Step 13To set preferences for all members, complete the following in the Set Preferences for All Members area:

Protection—Choose the member protection type:

– Fully Protected—Routes the circuit on a protected path.

– Unprotected—Creates an unprotected circuit.

– PCA—Routes the member on a BLSR protection channel.

– DRI—(Split routing only) Routes the member on a dual-ring interconnect circuit.

Node-Diverse Path—(Split routing only) Available when Fully Protected is chosen.

Step 14 Click Next. If you chose Fully Protected or PCA, click OK to continue. If not, continue with the next step.

Step 15 In the Route Review and Edit area, node icons appear so you can route the circuit manually.
